摘要
针对量子信号和经典信号在网络中混合传输的情况,为提升密钥生成效率和安全传输距离等性能,分析了PM协议的特点,提出了一个基于PM协议的量子-经典混合光网络方案,并对采用较远波段隔离方案的混合光网络性能进行了仿真。数值结果表明:PM协议的密钥生成率较高,安全传输距离较远,且密钥生成率随传输距离的增加而下降的趋势较缓。对于小型网络,PM协议的安全传输距离最远,且密钥生成率在长距离传输时具有优势;对于中型网络,PM协议与BB84协议依旧保持各自的优势,而MDI协议的性能最差;对于大型网络,BB84协议具有最好的性能,PM协议次之,MDI协议最差。
Abstract
Aim

ing at the mixed transmission of quantum signals and classical signals in the network, and through the analysis of the characteristics of the PM protocol, we proposes a hybrid quantum-classical optical network scheme based on PM protocol to improve the key generation rate, secure transmission distance, and so on. In addition, the QKD performance of the far-band isolation scheme is simulated. The numerical results show that not only the key generation rate of the PM protocol is high and the secure transmission distance is long, but also the key generation rate decreases slowly with the increase of transmission distance. For a small hybrid optical network, the PM protocol has the longest secure transmission distance and the highest key generation rate for long-distance transmission. For a medium-sized network, the PM and BB84 protocols still have their advantages, but the performance of the MDI protocol is the worst. For a large network, the performance of the BB84 protocol is the best, that of the PM protocol is the second, and that of the MDI protocol is the worst.
