High-speed Photon-Number-Resolution Quanta Imaging Sensor Array

Single-photon counting and timing achieves light detection at the fundamental quantum limit, unlocking next generation capabilities in quantum imaging and environmental sensing. Many applications require counting/timing photons at very high rates (>GHz), leading to instantaneous photon bunching (“pileup”) that causes photons to be missed. The result is data loss, degraded statistics and nonlinearities. Current detectors mitigate such deluges by breaking the flow of photons onto arrays of many sm...
