About IYQ-2025
The International Year of Quantum Science & Technology (IYQ), celebrated in 2025 to mark the 100th anniversary of quantum mechanics, helped raise public awareness of the importance and impact of quantum science and its applications on all aspects of life. Anyone, anywhere, was invited to participate in IYQ by helping others to learn more about quantum on this centennial occasion or simply taking the time to learn more about it themselves.
The IYQ 2025 was observed under the following guidlines:
No One Owns Quantum ScienceÂ
No individual, society, country, institution, or discipline can claim ownership of the past or future of quantum science; it is knowledge that should be free to all. IYQ recognizes those who put effort into studying, developing, investigating, using, and teaching quantum science and technology, while seeking to solicit and answer questions from anyone who wants to learn more about it.Â
Everyone was InvitedÂ
Those who have insights into the beauty, power, and importance of quantum science and technology were invited to use IYQ as a moment to share these insights with people who are less familiar with quantum. IYQ asked everyone to make an effort to reach out to people with different cultural backgrounds and aesthetic sensibilities.Â
Recognize Consensus, Honor Dissent, and Admit IgnoranceÂ
People inclined to present or seek out a unified story were asked to make note of where others dissent. Those inclined to highlight disputes and controversies were asked to recognize where there is consensus, and those who promote or understand established knowledge make note of what is still unknown.Â
Help Others Find Reliable Quantum InformationÂ
Many things have been and will be said about quantum science and technology that are untrue or misleading. The remedy for these statements is more quantum speech. All people proceed from learning simple, sometimes incorrect stories to deeper, more nuanced ones. IYQ aimed to meet people where they are in their understanding and help them to construct pathways for this journey.Â
Model the Ideals of Scientific ConductÂ
There is often a disparity between how we hope scientific inquiry is conducted and how it is actually practiced by individuals and institutions. IYQ is an opportunity to communicate and model the ideals of how science should be practiced in the hope that future generations will take up these values.Â
Be HonestÂ
Pride in the past and optimism about the future were welcome, and stories often have to be simplified out of necessity, but IYQ should always aim to foreground honesty about the past and future of quantum science and technology.Â
Have Fun!Â
Those whose lives quantum has brought joy to were invited to share this joy with others.
