## Abstract In order to realize longβdistance quantum cryptography based on standard optical fiber network, we have developed a singleβphoton 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
