摘要

本文讨论了由地球静止卫星(GEO)和低地球轨道卫星(LEO)组成的全球尺度自由空间光学/量子密钥分发(FSO/QKD)网络的设计。特别是，我们提出了一种使用双阈值/直接检测(DT/DD)方案的基于网络编码辅助混合纠缠/准备和测量(EB/PM)的卫星连续变量QKD (CV-QKD)的新实现。通过考虑大气湍流、接收机噪声和来自窃听者的未授权接收机攻击(URA)的影响，从最终密钥创建率方面分析了系统性能。此外，我们还以日本QKD网络现有的GEO和LEO卫星为例，探讨了该方法的可行性。

Network Coding Aided Hybrid EB/PM Satellite-based FSO/QKD Systems

This paper addresses the design of global-scale free-space optics/quantum key distribution (FSO/QKD) networks comprising geostationary (GEO) and low Earth orbit (LEO) satellites. In particular, we present a novel implementation of network coding aided hybrid entanglement-based/prepare-and-measure (EB/PM) for satellite continuous-variable QKD (CV-QKD) using a dual-threshold/direct-detection (DT/DD) scheme. The system performance is analyzed in terms of final key-creation rates by considering the effects of atmospheric turbulence, receiver noise, and unauthorized receiver attack (URA) from eavesdroppers. Also, we investigate the feasibility of a case study for the existing GEO and LEO satellites from Japan QKD network.
