The STAGE Center’s Quantum Journeys

We are STAGE—Scientists, Technologists, and Artists Generating Exploration—and this year, we’ve taken quantum play on a remarkable journey.

What began in our labs at the University of Chicago’s Pritzker School of Molecular Engineering (PME) has spilled into classrooms, campuses, fairs, airports, and international venues. The Center has created a suite of games called the Quantum Casino (also known as the Quantum Arcade and the Quantum Carnival). The Casino explores how cooperative and competitive game play can afford people from all walks of life a better intuition for and understanding of what quantum physics is, along with an appreciation for what advantages may be attained by leveraging quantum technologies. In the last six months, our Quantum Casino has traveled far beyond our Chicago campus in a wholehearted celebration of the International Year of Quantum.

The Quantum Casino is just one aspect of the collaborative work happening at the STAGE Center. At the heart of STAGE’s mission is the belief that creativity and discovery thrive at the intersection of disciplines. By bringing together artists, scientists, and technologists, the Center fosters a space where experimental ideas can take shape, leading to innovative approaches in both scientific communication and artistic creation. This multidisciplinary environment encourages collaboration that challenges traditional boundaries, ultimately generating work that not only entertains but also enlightens, sparking curiosity and deeper appreciation for science in audiences of all backgrounds. Bringing these ideas to life through our travels with the Quantum Casino has been an exciting way to see IYQ in action.

Our journey began in Japan, where we brought hands-on analog and digital quantum games to Tohoku University’s Open Campus, engaging hundreds of students encountering quantum ideas for the first time. Their excitement led to a return trip in October, deepening our growing partnership and demonstrating how cross-cultural collaboration can make quantum concepts accessible, joyful, and intuitive. From there, our work carried us to Paris, where we introduced our creative, art-science approach to new international audiences and with students from local elementary schools to university students at our host institution, Isep (the Paris Institute of Digital Technology). Back in the U.S., we continued our mission closer to home with a major presence at the Illinois State Fair in the tent of Governor JB Pritzker. There, visitors of all ages explored interactive exhibits that connected quantum ideas to everyday experience, proving that quantum outreach need not be confined to laboratories or universities.

Throughout these travels, our goal remained constant: to spark public interest in quantum science and technologies through creative storytelling and gameplay. These past months have reaffirmed our belief that science and art become most powerful when people can experience and explore them together. As the International Year of Quantum comes to a close, the STAGE Center is excited to continue creating fun pathways for quantum engagement and curiosity to thrive.

The Many Worlds of a Quantum Graduate

When quantum engineer Aitor Villar watched a rocket blast off from the US in November 2025, he was seeing almost ten years’ work take flight. This was the launch of SpeQtre—a satellite he helped design—set to demonstrate space-to-ground quantum communication.

Villar’s story is a wonderful example of the careers possible for students choosing a quantum path. His journey began with a PhD at the Centre for Quantum Technologies in Singapore. Arriving with a background in telecoms engineering, he started building quantum satellites, graduated to join a company spun off from the group, and has celebrated as the team’s first spacecraft entered orbit. Villar is part of a growing worldwide workforce in the emerging quantum industry. The total number of “quantum-engaged” workers globally may be close to 200,000, according to an estimate by the US-based Quantum Economic Development Consortium (QED-C) in its State of the Global Quantum Industry 2025 report. The consortium counted over 7,400 openings for quantum jobs in 2024 alone.

Career paths in quantum

These roles encompass a huge diversity. There are deeply technical and hands-on engineering jobs like Villar’s, but also software, business, and community positions. Take the roughly 100 students who have graduated from the PhD programme at CQT since 2007 as a sample: they have found a whole universe of opportunities.

Thi Ha Kyaw, for example, completed his PhD at CQT in 2018 in theoretical physics, focusing on quantum computing. He chose the software route. After a postdoc in Toronto, Canada, he joined LG Electronics, where he now leads a quantum computing research group. He settled in Canada but keeps strong ties to his student home: he is organising a conference in Singapore in 2026 to celebrate his PhD advisor’s 65th birthday.

Then there’s Angelina Frank. She went into the quantum industry, focusing on software first, taking a role as technical product manager at the Singapore HQ of startup Horizon Quantum after she graduated from CQT in 2023. During her PhD, she had organised camps for high-school students and co-established a national Quantum Young Researchers Association.  

Pursuing that community empowerment, Frank moved next to QAI Ventures, a Switzerland-headquartered venture firm that opened a Singapore office in 2025. She became their Head of Science and Technology APAC. The first project? Organising a quantum hackathon. 

Angelina Frank (right) developed a passion for community engagement during her PhD. She was part of the organising committee of QCamp, a week-long course for pre-university students at the Centre for Quantum Technologies.  Image: Centre for Quantum Technologies, Singapore.

Of course, the traditional path from PhD and to a career in academia is still there for students bitten by the research bug. Anurag Anshu, another 2018 CQT graduate, is now an Assistant Professor of Computer Science at Harvard University in the US. Meanwhile, Nelly Ng, who did a final-year project in CQT as an undergraduate before heading overseas for her PhD, came back as a CQT Fellow in 2025. This was after she was appointed an Assistant Professor at Nanyang Technological University, Singapore (NTU Singapore). 

What’s different these days is the variety of alternative employers competing for quantum skills. 

Top scholarships for talent

Seeing that demand for quantum-trained talent is intense and growing, Singapore in 2024 launched a National Quantum Scholarships Scheme. The programme will support up to 100 PhD and 100 Master’s students over five years. 

Lee Kai Xiang was among the first scholarship recipients. His project, part of Singapore’s National Quantum Processor Initiative (NQPI), involves building a neutral atom array computer. He got hooked by the idea of trying to build it and now enjoys problem-solving in the lab. 

NQPI is one of several national-level quantum programmes established under Singapore’s National Quantum Strategy to focus on translation and industry engagement, complementing the curiosity-driven basic research at CQT.

Through these programmes, students get to work on real-world applications. Recent CQT PhD graduate Du Jinyi, for example, collaborated with the National Quantum-Safe Network testbed to trial an exceptionally bright chip-based source of entangled photons over a record distance of 155 km of deployed telecom fibre. This kind of technology might be used to make a future quantum internet.

In another lab, PhD student Paul Tan worked with colleagues to integrate a superconducting quantum processor for the National Quantum Computing Hub using components from many suppliers. The processor will be used to explore how quantum computing could tackle challenges in fields from finance to drug discovery. 

Is the PhD essential? Not for all industry jobs. An analysis of quantum job listings by the Chicago Quantum Exchange, published in 2024, found that a PhD was a requirement for less than half. That can make a Master’s degree a good entry route, especially for students coming from different backgrounds who want to pick up quantum skills.

The Master’s scholarships under Singapore’s National Quantum Scholarships Scheme are tenable for selected existing courses where students commit to working on a quantum project. These include master’s by research programmes in physics, engineering, and chemistry. 

PhD scholars join CQT, matriculating at the National University of Singapore, NTU Singapore, or the Singapore University of Technology and Design, all of which host nodes of the national centre. 

Both scholarships offer attractive terms and are open to students of all nationalities. Undergraduate students can also ask CQT for an internship before they decide to apply.

With its clear strategy to be a hub for the development and deployment of quantum technologies, Singapore is fertile ground to launch a quantum career. Just ask Villar. While his PhD research aimed at space, he grew deep roots. The Spanish researcher, whose satellite will create quantum connections between countries, has chosen to call Singapore home. 

The diverse experiences of these PhD graduates still give only a small sample of the different types of career paths available in quantum. As researchers and engineers, they have joined a field that also needs educators, communicators, diplomats, economists, and policymakers. In Singapore and around the world, as the quantum industry grows, so do the opportunities.

Making Quantum Science Visible: Curating a Quantum Exhibit with the STAGE Center

If you’ve never seen a dilution refrigerator, or a “dil fridge” as we call it in the lab, it’s a surprisingly beautiful machine. A tall column of nested, gold-plated stages and intricate wiring hangs suspended several feet in the air, forming a structure that could be a piece of art in itself. For the next year, a model of one will be in the middle of O’Hare International Airport. 

On a recent trip through O’Hare, I stopped by the exhibit located in United Airlines’ Terminal 1. Before heading to my own gate, I stood for a bit and watched people walk around the glass case, read the captions, watch the video, and pull out their phones to scan the QR code to learn more. 

People heading to or from flights were drawn to the spectacle before they realized, “Oh, it’s science!”

As a quantum-track Molecular Engineering major at the University of Chicago’s Pritzker School of Molecular Engineering, it was deeply meaningful to see travelers pause to engage with the field that I study and love. Standing among them, I was struck by the quiet fact that no one knew I had helped build the exhibit they were exploring. 

The exhibit and accompanying informational website are called Imagining the Future: An Encounter with Quantum Technologies. I helped design both as part of UChicago’s Scientists, Technologists, and Artists Generating Exploration (STAGE) Center. Supported by a generous American Physical Society Innovation Fund grant with space donated by United Airlines, the exhibit celebrates the UN’s International Year of Quantum Science and Technology by putting quantum in public spaces. 

I care about finding ways to make quantum science more visible. Today, it’s hidden behind lab walls and layers of complex math, even as quantum technologies become increasingly relevant to everyday life. Biological sensors may one day detect diseases at the smallest levels, and quantum networks could create uncrackable, secure communications. And with resources like UChicago PME, the Chicago Quantum Exchange, Argonne and Fermi national labs, and a growing startup community, it is all centered right here in Chicago.

I came to the University of Chicago to be part of this quantum revolution and for the STAGE Center.

The STAGE Center, led by UChicago PME Prof. Nancy Kawalek, is a groundbreaking collaboration between engineers, physicists, artists, filmmakers and game creators working to tell stories about and inspired by science. For years, I have been passionate about both quantum physics and documentary filmmaking, and I’ve always been drawn to using narrative to make complex science approachable. The STAGE Center creates a rare environment for that intersection. 

When the United Nations announced 2025 would be the International Year of Quantum Science and Technology, I continued to think about how to make quantum visible to people. I wanted the public to not just become aware of quantum science, but to feel its relevance and the role it will play in their lives. I thought back to the first time I saw a dilution refrigerator, how striking and intricate it was, and how it invited a sense of curiosity long before I understood what it did. 

I envisioned an exhibit that would place a dilution refrigerator in a public space as a centerpiece. I brought the idea to Prof. Kawalek and STAGE Director of Science Sunanda Prabhu-Gaunkar. It has been remarkable to watch that initial spark of “Let’s put quantum in public” grow into this very real exhibit, now greeting the millions of travelers who pass through the terminal each year.

It was important to us that the exhibit would be genuinely educational, not just showcasing an incredible piece of hardware, but also the science behind it. Over several months, a team of five University of Chicago students—Jeffrey Li, Avery Linder, Reet Santosh Mhaske, Rohan Venkat, and myself—worked to develop the exhibit’s educational materials, including a website designed to help travelers understand what they’re looking at and why it matters. 

We wanted the science to be both accurate and accessible, a balance that is difficult to hit. Oversimplifying risks losing the integrity or accuracy of the science, but too many details can be overwhelming and turn people away. So we thought carefully about our audience, how much time they might spend at the exhibit, and what type of information would be engaging in that brief encounter.

Luckily, the STAGE Center has always done a very good job of making science accessible and exciting in all its projects. Under Nancy and Sunanda’s guidance, the exhibit grew into what you can see today. 

Working together, APS, United, IBM and the STAGE Center team put science where people would least expect to encounter it. 

In traditional museums or classrooms, people choose to seek out science. In an airport, it finds them where they are. As I continued to my gate, I kept thinking about the travelers who had paused to engage with quantum science in the middle of their journey. I’m sure they had no idea they would learn anything about quantum today, yet the exhibit made space for curiosity anyway. That, to me, is the power of bringing science into public life.

“Dedicated, Inspiring, and Supportive”; UNESCO 2025 International Year of Quantum Science and Technology Announces Quantum 100 to Celebrate Global Community

Major initiative spotlights 100 professionals helping to propel the field forward 

Maryland, USA – 17 December 2025 – The International Year of Quantum Science and Technology (IYQ), a United Nations-declared year, today announces the launch of the Quantum 100: a global snapshot of careers & community to recognize and champion people around the world who are working to advance research, innovation, and education. The announcement follows a worldwide call for nominations, which resulted in more than 400 submissions from five continents, telling the stories of hundreds of dedicated people contributing to scientific discovery, translation, policy, mentorship, education, and public engagement. 

While 2025 has seen quantum information science and technology come to the forefront of the global agenda, its progress will be limited without international cooperation, education, responsible innovation, and robust quantum research and development spanning academia and industry. The Quantum 100 showcases the many ways people are contributing to and advancing this field globally, and especially the importance of providing opportunities for aspiring professionals and scientists. 

The Quantum 100 were selected by members of the IYQ steering committee and global coordination bureau, composed of representatives from each of the IYQ Founding Partners as well as leaders around the world from universities, research institutions, scientific societies, governments, and industry. 

Representing people at every stage of their professional journey, the Quantum 100 spans academia, industry, education, art, journalism, and policy, reflecting a breadth of skills and specialization. The full Quantum 100 list can be found on the IYQ website, with a dedicated page for each person to showcase their accomplishments. From leading research in quantum computing, networking, and sensing, to international collaboration and policy-making, to reaching underserved communities through outreach and local engagement, the Quantum 100 encapsulates creativity, innovation, and scientific excellence. 

“It has been a privilege to read the Quantum 100 submissions and hear about so many dedicated, inspiring, and supportive professionals who give so much to quantum science and technology,” said Andrew Forbes, Distinguished Professor within the School of Physics at the U. Witwatersrand (South Africa) and member of the IYQ Steering Committee. “Their varied perspectives, experience, and backgrounds reflect the range of skills needed for advancing this field and ensure the next 100 years of quantum are as impactful as the first.”

Bridging the Quantum Divide Beyond the International Year of Quantum

The United Nations declared 2025 as the International Year of Quantum Science and Technology (IYQ), celebrating 100 years since the discovery of quantum mechanics and raising global awareness of the rapidly developing technology and its applications. 

As quantum technologies continue to evolve rapidly, their transformative potential also raises concerns about the uneven distribution of expertise and resources worldwide. With these advancements geographically concentrated, it’s easy to imagine a future where the technology is in the hands of and benefits a select number of nations. This situation risks widening the already existing divide between the Global North and South, as such concentration of control amplifies the uneven distribution of skills, infrastructure, and opportunities on a global scale. 

The Open Quantum Institute (OQI), hosted at CERN for its pilot phase, is working to mitigate this divide through practical, forward-looking efforts that will be sustained beyond the IYQ. Avoiding the widening of these gaps involves more than just developing new quantum algorithms or identifying new technological breakthroughs; it requires building and sustaining inclusive ecosystems in all regions, where stakeholders, including researchers, policymakers, and citizens, can actively help shape as well as benefit from the technology. 

Capacity building in action

Throughout the year, OQI has contributed to the IYQ through organising and supporting more than 30 events across five continents, with a pipeline of educational events planned for 2026 to sustain momentum beyond the IYQ.

One of OQI’s main efforts is driving global capacity building. In 2025, over 380 participants in hackathons across quantum-underserved regions had the opportunity to develop their quantum computing skills. During these hackathons, participants worked collaboratively to develop algorithms that address locally relevant challenges and advance the UN Sustainable Development Goals (SDGs). OQI’s educational activities throughout the IYQ also included the Quantum Diplomacy Game, a role-play simulation designed to raise awareness and anticipation of the geopolitical implications of quantum computing as an emerging technology, and regional events around the world—all with the collective aim of fostering the sharing of knowledge and open-access resources globally. 

SDG-aligned use cases 

Another core pillar of OQI is focusing on developing quantum computing applications that address the SDGs and contribute towards mitigating the existing divide. OQI supports the development of SDG use cases and fosters collaborations between experts around the world to guide their progress from ideation to proof-of-concept and implementation on today’s quantum devices. Taking a multidisciplinary approach has proven essential, bringing together research, diplomacy, philanthropy, academia, industry, and civil society to amplify impact on a global level. 

Beyond the IYQ

Alongside raising public awareness, the IYQ also identified a range of challenges to be overcome, including limited access to the technology in underserved regions and identifying governance gaps that highlight the need to develop inclusive frameworks. As the global quantum community reflects on the successes and lessons learned, an emphasis on sustained international collaboration will be essential to continue nurturing a diverse global ecosystem and to further mitigate the divide, showing a clear path towards ensuring the technology is advanced inclusively and for the benefit of all humanity.

The Quantum Year 2025 in Germany: A Vibrant Mix of Activities

With a wide range of activities, national and international scope, and strengthened partnerships, the German Physical Society (DPG) is closing the Quantum Year—an outstanding example of volunteer work.

A memorable closing event on November 15, 2025, marked the end of the activities of the Quantum Year in Germany. The DPG took the lead in implementing the International Year of Quantum Science and Technology (IYQT) in Germany. Under the motto “Quantum2025—100 years is just the beginning…,” a large number of events and activities were organised, mostly by volunteers. These activities were aimed at anyone interested in quantum phenomena, including pupils, researchers, industry professionals, artists, history enthusiasts, or simply the curious.

The DPG honoured this special year with a national opening ceremony, attended by representatives from 15 physical societies, and a closing ceremony, attended by 3,000 members of the wider public. In addition, a joint DPG autumn conference was held in Göttingen, the birthplace of quantum mechanics, which was specifically dedicated to the significance and modern developments of quantum mechanics. Recurring DPG events were placed under the motto of the Quantum Year, such as the annual DPG Spring Meetings, with around 8,000 participants. Ghana was the country of honor at the annual conference in Bonn and was represented by a delegation to honour Ghana’s role in the United Nations’ proclamation of the IYQ.

New momentum in science communication

In the field of research and science communication, new projects connected science with the public: for example, a quantum light source travelled across Europe, accompanied by social media posts and numerous publications. The project received several awards. In addition, an online map was created highlighting quantum physics institutions in Germany. Each of these received a building plaque to draw attention to quantum physics locally. “Over the course of one year, the DPG’s quantum activities could be found everywhere, in cities and physics institutes, on the internet, in social media, in schools, in libraries, and even in museums and cinemas,” summarizes DPG President Klaus Richter. In addition, interactive elements were developed to illustrate the history of quantum mechanics, and initiatives were launched to highlight the significant but often overlooked contributions of women to quantum physics. These resources remain available beyond the Quantum Year.

All these activities were made possible by members of the DPG, who developed and implemented ideas well in advance of the Quantum Year. Special thanks also go to the Wilhelm and Else Heraeus Foundation, whose financial support made many projects possible in the first place.

Impact beyond the DPG

With its official website, www.quantum2025.de, the DPG provided a central calendar during the Quantum Year, listing more than 400 quantum events in Germany. An exhibition and the national closing event were held under the patronage of the DPG, and partnerships with cities were established. The DPG also reached an international audience through livestreams and international partnerships, e.g., through cooperation with the European Physical Society on the EPS Declaration “Europe and the Future of Quantum Science” and with the Physical Society of Japan on the “Declaration for the Future.” “We have successfully brought the topic of quantum physics to the public’s attention and made clear that it is a powerful cultural, social, and economic development that will influence our social lives,” emphasizes Dieter Meschede, coordinator of the DPG Task Force Quantum Year and former president of the DPG.

At the international level, the International Year of Quantum Science and Technology will be officially closed in February 2026 in Accra, Ghana.

Nathalie P. de Leon, the Diamond Scientist Pushing the Quantum Technology Frontier

Interview with Dr. Nathalie P. de Leon, Associate Professor of Electrical and Computer Engineering, at Plasma Physics Laboratory, Princeton University

Beyond beauty and rarity, diamonds have been used by scientists due to their exceptional hardness and resistance to pressure to build instruments like ultra-thin knives for electron microscopy samples, or in powders to polish materials. However, diamond’s quantum properties have also been shown to be crucial for cutting-edge applications, sometimes even if they are impure, those that would be rejected in the jewelry business. 

We interviewed Nathalie P. de Leon, a physicist leading a research group in Princeton, New Jersey, that turns pure diamonds into defective diamonds to push the frontiers of quantum applications, such as quantum computers, sensors, and communication networks. 

“What we do is that we kick out one or two carbons of the diamond and replace it with something else, then we get a little defect that responds to light in a different way than the carbons,” Nathalie explains. “The interesting aspect about these imperfections, in the quantum world, is that some of them have high efficiency in the sense that they absorb a photon and then spit a photon back out, so that they act as single photon sources.”

These “imperfections” are called color centers, tiny defects placed with atomic precision inside the diamond’s crystal, causing the diamond to behave like a single atom from a quantum perspective. What others call a flaw, Nathalie sees as a priceless feature.

“The term ‘color center’ is very old; it is really just about shining light that gets absorbed and light that gets emitted; then, the color center is what makes the diamond look yellow or blue. These color centers are defects in the diamond that give us very localized quantum states that we can use in many applications.”

Building Quantum Devices from Flawed Diamonds

Nathalie uses nitrogen to replace the carbon vacancies to create her color centers, called “NV centers.” Then, she and her team manipulate and measure quantum properties of the NV center’s electrons with extraordinary precision. One of these manipulable quantum features is the electron’s spin. The spin is a fundamental quantum-mechanical property found in elementary particles, such as electrons and quarks, and in composite particles, such as protons and atoms, that can have specific values. For example, the electron’s spin can have two values that physicists call “spin up” and “spin down” (or ½ and – ½ ), and it is responsible for the magnetic properties of the electron.

Unlike most quantum systems, which must be kept at extremely low temperatures, NV centers in diamonds can operate at room temperature, a rare advantage in emerging quantum technologies that desperately need long coherence times (the time the system can maintain a quantum state). This unique property makes them among the few quantum platforms that can operate outside specialized cryogenic environments (extremely cold temperatures), opening the door to practical quantum technologies. 

“The main reason why these NV centers are really exciting is the very long spin coherence time, the longest coherence time anyone has ever measured at room temperature and ambient conditions, so you have milliseconds of coherence time, which is really remarkable because you can use the electron’s spin up or down to store quantum information. It also has very efficient optical transitions, which means I put one photon in and get one photon back out.”

Diamonds, Light, and the Quantum Frontier

Nathalie’s research lab has shown that these engineered diamonds are more than just scientific curiosities—they can serve as information storage and processing devices, sensors, and building blocks for quantum communication. De Leon focuses on using NV centers as quantum sensors to measure magnetic fields with extremely high precision and spatial resolution, opening a new frontier in which quantum sensors can help us discover new materials, perform biomedical diagnostics, and aid navigation. Her lab works on the full gamut from basic research to applied technologies, innovating diamond growth in collaboration with Alastair Stacey at the Princeton Plasma Physics Laboratory, devising new sensing schemes, and making integrated sensing devices.

In a 2022 Science paper, her group showed that NV centers could be used to directly measure correlations in magnetic noise, a new physical quantity that is not measurable by any instrument today.  A follow-up paper (in press in Nature) showed how entanglement can be harnessed to improve these measurements. In a 2025 paper in Physical Review X, Nathalie and her team report a breakthrough in studies of nitrogen color centers in diamonds. Traditionally, researchers could study only one diamond color center at a time—a slow process that limited what they could learn about collective quantum behavior. De Leon’s group changed that, creating a system that can read signals from hundreds of nitrogen vacancy centers simultaneously. 

With this innovation, scientists can create tools that can track how tiny magnetic fields vary not just at single points, but across entire 100-micrometer-scale regions. These tiny devices could help advance the study of exotic materials or the development of medical instruments.

Science as a Game of Risk

For Nathalie, research is about strategic exploration. After she showed how to control the surface of diamond to make near-surface NV centers behave well, she started a new collaboration with Andrew Houck and Bob Cava to tackle a completely different platform—improving the quantum coherence of superconducting qubits, which had been stagnant for about a decade despite enormous worldwide investment. In five years, this collaboration has yielded two major improvements in superconducting qubit coherence, first from 100 microseconds to 300 microseconds (Nature Communications 2021), and then to over 1.5 ms (Nature 2025). Jumping into a new effort required devising a large-scale, interdisciplinary playbook to measure and tackle many different aspects of the qubit at once, which she describes in a recent 2025 Nature Physics comment. She compares it to playing Risk, the board game where players place pieces, roll dice, and attempt to conquer new territories. In her view, science works in a similar way. 

“You can think of many of these projects as a giant Risk board game. What we are doing is placing forces in different parts of the board because we want to advance the state of the art in some technology. We created qubits made with tantalum and achieved a factor-of-three improvement over the state of the art. And then, we ask, can we do better? And I also need to be aware of the different forces and that other people are working on a different part of the game. For example, now we have one millisecond of coherence, so, how can we make that into 10 milliseconds? We have efforts tackling new materials and better fabrication, but also on packaging and filtering, understanding when the coherence is worse than the loss, measuring time variation… The frontier does not care about what instruments we already have in the lab or what knowledge I have in my head. So, we spend a lot of time figuring out how we are going to solve that problem and advance on the board.” 

From blowing up things in her parents’ garage to Harvard, Princeton, and beyond

As a child, de Leon’s curiosity stretched in every direction—from music and art to debate and journalism. But beneath all those interests was a restless fascination with how the world worked. Growing up in a place with few outlets for kids drawn to science, she pursued science as a hobby at home, mixing chemicals and experimenting with crystal growth—sometimes a little too enthusiastically. 

“I was mixing chemicals in my garage. I almost blew my fingers a couple of times,” she laughs. “I was interested in crystal growth; I found that exciting, the purification and patience, and I still have a fondness for crystal growth.”   

What began as a love for crystals evolved into a career uncovering the quantum secrets hidden inside them, a trajectory that has been anything but linear. From chemistry at Stanford to a PhD in chemical physics at Harvard University, by the time de Leon reached graduate school, her path had already begun to twist in unexpected directions. 

De Leon joined as an assistant professor at Princeton in 2016. Since then, she’s earned a collection of early-career honors—from the U.S. Department of Energy, DARPA, and the National Science Foundation—as well as a Sloan Research Fellowship. She was also awarded the APS Landauer-Bennett Award in 2023 for her work in quantum computing. Currently, she is an Associate Professor of Electrical and Computer Engineering at Princeton University, a co-Director of the Princeton Quantum Initiative, and an associated faculty member of physics, as well as at the Princeton Plasma Physics Laboratory. She is also a Visiting Research Faculty at Google Quantum AI. With her research, Nathalie helps bridge the gap between fundamental physics and engineering.   

“These are very exciting times to be living through,” Nathalie concludes.

What Y2K Can Teach Us About Q-Day

(The Quantum Algorithms Institute is an IYQ sponsor.)

Quantum computers are a powerful emerging technology that could solve some of the world’s most complex problems. Unfortunately, one of those problems includes breaking our most widely used encryption algorithms, compromising massive amounts of data worldwide. 

But in 2025, this should not be news. The quantum threat to cybersecurity has been a hot topic for years, with many organizations working to remediate it. Recently, the US National Institute of Standards and Technology (NIST) has released three standardized “quantum safe” encryption algorithms, marking a huge milestone in post-quantum cybersecurity development. So, with these new safe encryption mechanisms, isn’t this threat now neutralized? Unfortunately, not yet.

The emergence of new encryption standards and national migration guidelines is only the first step in the post-quantum security process; getting organizations to implement these new standards in time, before large-scale quantum computers emerge, is a far more daunting task. 

Due to the unpredictable nature of quantum computing progress, skepticism about the validity of the quantum threat, and, most importantly, the lack of a distinct Q-Day deadline, the atmosphere surrounding post-quantum cryptography migration shows a considerable lack of urgency that could prove detrimental in the future. 

PQC Inaction and Comparison to Y2K

In 1999, as the world was speeding towards a new millennium, the Y2K Bug was on everyone’s mind. Because computers at the time stored the current year as only two numbers (99 for 1999, 98 for 1998, and so on), the fear was that once the year 2000 hit, computer systems around the world would interpret “00” as “1900” rather than “2000.” This bug was predicted to shut down critical infrastructure technology unless taken care of. 

The hard deadline of January 1st, 2000, pushed organizations and governments to solve the problem before it was too late. An estimated $300 billion USD was spent worldwide to fix the bug, and, due to the hard work of thousands of workers behind the scenes, the impact of the Y2K bug was largely mitigated.

The Y2K bug is eerily similar to the newly dubbed Q-Day, the day quantum computers will break modern encryption. If/when this breakthrough event does occur, the implications will be far greater than those of Y2K, rendering the majority of modern encryption obsolete. So, why aren’t we seeing the same urgency to solve the Q-Day problem?

Quantum Doubt and Portrayal in Media

Unlike Y2K, quantum computing’s timeline and image make it harder to mobilize. There were a few traits to Y2K that enabled it to be taken seriously by not only the technology workers trying to fix the problem, but most importantly, by influential company executives. 

The tangible deadline certainly helped executives take the problem seriously. Significant pressure was applied, pushing organizations to act sooner rather than later. In contrast, because Q-Day could be anywhere from 3 to 15 years away, according to analysts, it is challenging to convince organizations to allocate resources to the problem now. 

The way that the Y2K problem was comparatively easy to understand and quantify also had a large impact on how it was handled. The Y2K bug was easy to take seriously in part due to its mundane nature. In contrast, the quantum threat may seem technologically far-out to most, with some dismissing it entirely as science fiction due to the often-inaccurate portrayal of quantum technologies in popular media. Superhero movies, sci-fi adventures, and space operas all use the term “quantum” to describe just about anything adjacent to magic, causing “quantum” and “sci-fi” to share the same brain space. 

This portrayal makes it difficult for outsiders to take quantum seriously. Ella Meyer, a quantum computing outreach coordinator at the University of British Columbia, told GeekWire that media portrayals like this are making it “harder than ever to get people to properly engage with this world.”

Executives and key decision makers around the world are still trying to wrap their heads around the equally sci-fi-like world of AI, and now they’re being told they must start dealing with seemingly outlandish quantum threats.

Because of the lack of a hard deadline and the fantastical portrayal of quantum in fictional media, it is easy to see how difficult it can be for non-technical decision-makers to take the quantum threat seriously. 

Call to Action

It is vital to the security of all organizations to get executive minds on board with the quantum threat. This isn’t simply something to be ignored. Already, national post-quantum migration roadmaps have been released by the likes of Canada, the USA, and the UK.

The migration to post-quantum cryptography will be long and arduous for most organizations. Convincing an executive team to commit to a multi-year-long project defending against such a fluid threat will be difficult, but it is entirely necessary. 

When discussing the quantum threat with executives, make sure to speak their language. Don’t get caught up in superposition and qubit count, but instead point to government migration guidelines and the post-quantum security plans of large corporations.

Additionally, highlight how migrating to post-quantum cryptography will improve an organization’s security posture beyond the quantum threat. Upgrading to new, improved cryptography, developing ways to become cryptographically agile, and undergoing a cryptographic discovery process will all help defend governments, businesses, and utilities against both quantum and classical threats. 

An organization’s post-quantum cryptography migration doesn’t have to be handled entirely in-house, either. Recently, new and established vendors, such as IBM, PQShield, and SandboxAQ, have begun offering cryptographic discovery and post-quantum remediation services. For organizations with small security teams, such vendors provide essential assistance. 

Conclusion 

In a world where the status quo on security and technology is constantly changing, it can be challenging to sift through the noise and find what will truly make an impact. The Y2K bug was taken seriously because it was perfectly positioned to cut through that noise due to its hard deadline and grounded nature. 

The quantum threat to cybersecurity is different. There is no hard deadline, no immediate observable impact, and it is obstructed by the mythological portrayal of a very real technology. Nevertheless, actions to mitigate this threat must be taken.

Every delay in migration extends the period in which critical data remains exposed to future decryption. The growing concern of “harvest now, decrypt later” attacks—where adversaries stockpile encrypted data anticipating quantum capabilities—makes early action essential.

The threat must be properly communicated to executive minds. Point to existing government migration guidelines, avoid getting caught up in the technical weeds, and make it clear that this is a threat that cannot be ignored.

The International Quantum Business Conference 2025: A Joint Initiative by the Galician Government, CESGA, and Fsas Technologies—a Fujitsu Company

(Fujitsu is an IYQ sponsor)

Quantum technologies are entering a decisive moment. Once considered a far-off scientific ambition, they are now moving steadily into practical experimentation, hybrid computing frameworks, and early industrial use cases. The shift is global, multidisciplinary, and collaborative. And yet, in many organizations, quantum still feels like a future tense: promising, but not ready; exciting, but uncertain.

The International Quantum Business Conference, taking place in Santiago de Compostela on December 17 to 18, 2025, is designed precisely for this moment. It brings together industry leaders, researchers, technologists, policymakers, and investors to discuss what it means to move quantum from potential to capability, and from capability to impact.

Pioneering Quantum Innovation from Galicia

Fsas Technologies—a Fujitsu company’s International Quantum Center was created with a clear mission: to accelerate the adoption of quantum technologies by fostering collaboration between research, industry, and public institutions. In Galicia, this mission has taken shape through concrete achievements—from pioneering proof-of-concept pilots with regional industry to the launch of specialized university courses that help cultivate the next generation of quantum talent. This new generation will have the opportunity to join research and development initiatives with the Galician Supercomputing Center (CESGA), local clusters, and innovation agencies. Together with the Galician government and CESGA, these efforts have laid the foundations for a robust quantum ecosystem that is internationally visible and growing rapidly.

More Than a Meeting Point—A Blueprint for Progress

Launched in 2024 by Fujitsu, in collaboration with the Galician Supercomputing Center (CESGA) and GAIN (The Galician Government’s Innovation Agency), the conference established itself as a unique forum where the scientific and business dimensions of quantum met on equal footing. The first edition gathered more than 200 participants from business, academia, and government, with a strong presence of international speakers and media coverage.

Discussions last year ranged from European public initiatives and global investment trends to real-world applications of quantum for drug discovery, logistics, energy optimization, and finance. This year’s edition continues that spirit, while raising the stakes.

2025: Empowering the Future of Quantum and Supercomputing for AI

As hybrid cloud environments, advanced accelerators, and quantum resources begin to work together, the frontier is no longer quantum alone, but quantum + HPC + AI. This is the landscape the 2025 program explores.

Across two days, participants will engage in:

  • Keynotes on European quantum strategy and national-scale ecosystem development
  • Panels connecting R&D centers, investors, and emerging industry adopters
  • Scientific sessions on quantum hardware, algorithms, and hybrid architectures
  • Business track discussions on real deployment pathways, funding, and regulation
  • A parallel poster session and a visit to the CESGA Quantum Computer (QMIO)

The conference also hosts the QUORUM alliance sessions, focused on Spain’s collaborative quantum innovation efforts across research centers and companies.

Why It Matters Now

Across regions and markets, the same questions echo:

  • How do we build a quantum-ready workforce?
  • Which applications will mature first?
  • How should policymakers support competitiveness while ensuring ethical and strategic alignment?
  • What partnerships enable scalable innovation rather than isolated pilot projects?

This event is shaped to address these questions practically, not hypothetically.

Speakers include leaders shaping quantum research, ecosystem design, industry deployment, and science policy. Topics such as fault tolerance, quantum-safe communications, dual-use innovation, hybrid quantum-HPC architectures, and sectoral case studies illustrate what scaling pathways may look like over the next five years.

The Place Matters Too

Santiago de Compostela has become an unexpected yet fitting landmark in Europe’s quantum map. With Fujitsu’s International Quantum Center, the Galician Supercomputing Center (CESGA), and a growing network of research institutions and technology companies, Galicia is positioning itself as a European node for quantum talent, experimentation, and industry collaboration.

The conference is part of that story of ecosystem-making.
