## Abstract In order to realize long‐distance quantum cryptography based on standard optical fiber network, we have developed a single‐photon detector at 1550 nm using InGaAs/InP avalanche photodiodes (APDs). To reduce the dark count probability, APDs were cooled and operated with a Gated Passive Q
