Quantum computers are at the forefront of emerging technologies, with trapped ions and neutral atoms among the most promising platforms under development. These systems depend critically on photonics for qubit state detection, using the presence or absence of fluorescence—captured via emitted photons—to determine the quantum state of atoms or ions. This webinar offers a comprehensive overview of both trapped ion and neutral atom architectures, emphasizing the role of photonics in reliable and efficient qubit state readout.

Attendees will gain insights into the latest detection and imaging technologies used for qubit readout and mid-circuit measurement, including PMTs, SPADs, EMCCD cameras, and the ORCA-QUEST 2 qCMOS camera. The discussion will cover key trade-offs in speed, sensitivity, system integration, and scalability. The session will conclude with a forward-looking perspective on the challenges and innovations that will shape the future of qubit detection and photonic integration in next-generation quantum processors.
