Analysis of the Influence of Atmospheric Haze on Quantum Satellite Communication Multi-channel Performance

Abstract— In quantum satellite communication, when the optical quantum signal is transmitted between satellite and ground links, it will be affected by various natural environments. At the same time, haze has become one of the largest environmental problems in the world. Therefore, it is of great significance to study the communication performance of quantum satellites in haze atmosphere. In this paper, according to the scale distribution and vertical spatial concentration change of large aerosol haze particles, the extinction characteristic model of large aerosol haze particles and the attenuation model of atmospheric haze particle concentration and transmission height on quantum satellite ground link are established. Some important performance parameters in quantum satellite communication are analyzed for amplitude damping channel, depolarization channel and phase damping channel respectively, It includes the quantitative relationship between channel capacity, quantum fidelity, quantum bit error rate and entanglement and large aerosol haze particle concentration and transmission height. The simulation results show that with the increase of transmission distance and haze particle concentration, the channel capacity, quantum fidelity and entanglement of quantum satellite communication in different channels will decrease, and the bit error rate will increase. Therefore, the impact of large haze environment on quantum satellite communication should be fully considered in the actual process of quantum satellite communication, Adaptive adjustment of relevant parameters to ensure the normal operation of quantum satellite communication.

Index Terms— Quantum satellite communication, The aerosol haze, The channel capacity, Quantum bit error rate, fidelity.
