Abstract

This work is dedicated to the problem of noise reduction of single photon detector development based on InGaAs-InP avalanche photodiodes. Dark count probability and quantum efficiency of the detectors have been measured. We present the experimental fiber based quantum key distribution setup with phase coding of single photon states. The autocompensation two way optical scheme (plug&play) is used. The single photon source is the strongly attenuated laser pulse which goes through two paths of Mach-Zehnder interferometer where it undergoes the phase coding. Quantum channel is formed by 25 km single mode fiber. To generate the quantum key the four phases BB84 protocol is used.
