论文摘要
连续可变的量子密钥分布（CV-QKD）可以允许QKD和经典的光学信号在现有网络中物理共享相同的光纤。但是，拉曼散射对光电功率施加了限制，这反过来影响了在CV-QKD存在下经典流量的网络容量。网络计划模拟表明，在光学链路上最大化CV-QKD容量可能会对其经典能力产生不利影响。尽管初步的结果表明，设计混合的古典和CV-QKD网络将需要专门的计划启发式方法和工具，这些计划和工具专门寻求经典和CV-QKD贩运者之间的妥协。
Continuous-variable quantum key distribution (CV-QKD) could allow QKD and classical optical signals physically sharing the same optical fibers in existing networks. However, Raman scattering imposes a limit on the optical power, which in turn impacts the network capacity for classical traffic in presence of CV-QKD. Network-planning simulations indicate that maxing out the CV-QKD capacity in an optical link can adversely impact its classical capacity. Although preliminary, these results show that designing a mixed classical and CV-QKD network will require dedicated planning heuristics and tools that specifically seek a compromise between classical and CV-QKD traffics.
