摘要
在考虑大气湍流及气动光学效应的情况下,建立了航空平台连续变量量子通信系统的传播模型,数值分析了信道特性对系统安全密钥率的影响。结果表明,大气湍流的折射率结构常数越小,气动光学影响下折射率结构常数的变化对系统安全密钥率的影响越明显;大气湍流及气动光学效应对系统安全密钥率的影响不容忽视。根据大气信道特性,通过设计相应的系统补偿模块,自适应地调整量子通信系统的相关参数,可以增强系统的稳健性。
Abstract
The propagation model of a continuous variable quantum communication system on an airborne platform is established in the case that the atmospheric turbulence and aero-optical effects are considered. The influence of channel characteristic on the security key rate of this system is numerically analyzed. The results show that, the smaller the refractive index structure constant of the atmospheric turbulence is, the more obvious the influence of the change of the refractive index structure constant on the security key rate of this system is. The influence of the atmospheric turbulence and the aero-optical effect on the security key rate of the system cannot be ignored. According to the atmospheric channel characteristics, the corresponding compensation module for this system is designed to adaptively adjust the relevant parameters of the quantum communication system so as to enhance the robustness of the system.
