Presentation Title:
Single-photon camera system based on Superconducting Nanowires
Presentation Abstract:
As quantum technology matures, the need for larger systems for sensing single photons is becoming stronger. We are gearing up for this with a modular approach to scaling up our photon detection systems. This is best illustrated by our SNSPD array system with 10×10 independently addressed SNSPDs with > 55% efficiency at 1064nm, approximately 100ps jitter, a count rate > 6 MCPS per pixel for scalable single-photon imaging, quantum sensing and LiDAR. This is the largest commercial independently addressed superconducting nanowire single-photon detector (SNSPD) array reported to date: a fully functional 10 × 10 pixel system offering high detection efficiency, fast timing performance, and high count-rates. This platform represents a significant step toward large-format, high-throughput SNSPD cameras. Its combination of efficiency, speed, and parallelism can open the way to advanced quantum imaging, long-range time-of-flight LiDAR, fluorescence lifetime microscopy, and more generally, any photon-correlation experiments requiring precise timing and spatial resolution. Informed by these results we are also working on scalable platforms for large systems that are fiber-coupled.
