单光子卫星量子通信噪声和干扰分析
Analysis of Noise and Interference to Single Photon Satellite Quantum Communication
摘要
Abstract
Satellite quantum communication is one of the best choices for building a global quantum net-work. In view of the polarization maintaining problem in satellite quantum communication which uses po-larization encoding, the impact of atmospheric scattering and relative movement between satellite and ground station on the photon polarization states’ phase and alignment and the influence of alignment error and phase delay on quantum bit error rate of the system is researched. The influence of background noise and hardware on the quantum communication and the photon-number-splitting attacks to the single photon in quantum communication are analyzed. Research in this paper has important significance to quantum sig-nal’ s cognitive design.关键词
