Catching Photons, Decoding Qubits: Unlocking Qubit State Readout with Trapped Ions and Neutral Atoms
10 July 2025 10:00 - 11:00
Eastern Daylight/Summer Time (US & Canada) (UTC -04:00)Quantum computers represent a rapidly advancing frontier in technology, with trapped ions and neutral atoms being two of the modalities under active investigation. These platforms rely heavily on photonics, particularly for qubit state detection. The presence or absence of fluorescence-captured through emitted photons-provides critical information about an atom's or ion's quantum state. This presentation will provide an overview of trapped ion and neutral atom systems, focusing on the crucial role of photonics in qubit state readout. We will examine the detector and imaging technologies currently deployed for qubit state readout and mid-circuit readout-including PMTs, SPADs, EMCCD camera, and ORCA-QUEST 2 qCMOS camera-and discuss the trade-offs between speed, sensitivity, integration, and scalability. Finally, we will highlight forward-looking challenges and innovations that will define the future of qubit detection and photonic integration in quantum processors.
