Abstract:
A ground receiving station for satellite quantum key distribution capable of analyzing the quantum polarization states of photons is presented. In an experiment concerning tracking a low-Earth orbit satellite, the residual tracking error by the ground station does not exceed 10 $\mu$rad, which ensures stable reception of the optical signal in four channels of the polarization state decoder. The efficiency of optical-signal recording in the satellite tracking mode is estimated.
Keywords:
quantum key distribution, quantum communications, single photon detector, artificial satellite of Earth.
