## 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

## Abstract We experimentally demonstrate the compatibility of wavelength multiplexed active polarization stabilization for quantum communication in an optical fiber carrying telecom traffic. One of the feedback control channels contains a 9.953 Gb/s datastream generated from a BER meter. We verify
