Abstract:

A satellite-to-ground quantum key communication simulation platform is designed considering the present situation of complex space environment and temporarily unavailable experiment condition domestically. The system is capable of simulating APT and single-photon transmission and capture processes and of correcting wavefront distortion by adaptive-optic. Rational simulation results of tracking and pointing accuracy, AO correction, single-photon acquisition probability,and error rate are obtained by using the system and will be useful in designing actual systems.

Key words: satellite-to-ground quantum key, simulation, APT, adaptive-optic, acquisition probability and error rate
