Abstract
We report on a high-efficiency multipixel SNSPD array detecting at > 1.5 GHz and that has excellent photon-number resolving (PNR) capability at 1550 nm. This device enables ultrafast QKD with > 60 Mbps secret key rate, and also PNR detection with high n-photon efficiencies for photonic quantum processors with various types of photon sources.
