论文摘要
量子密钥分布（QKD）网络构成了安全通信的有希望的解决方案。除了传统的点对点QKD之外，我们还开发了具有子NS分辨率光路径薪酬方案的1XN QKD网络系统。通过基于字段可编程门阵列（FPGA）的实用插件QKD体系结构和紧凑的正时控制模块，我们实现了1x64 QKD网络系统的长期稳定操作。使用此体系结构，64个用户可以同时与一台服务器共享秘密密钥，而无需使用复杂的软件算法和昂贵的硬件。我们使用大都市区的光纤网络展示了1x4 QKD网络系统的工作。
Quantum key distribution (QKD) networks constitute promising solutions for secure communication. Beyond conventional point-to-point QKD, we developed 1xN QKD network systems with a sub-ns resolution optical path length compensation scheme. With a practical plug-and-play QKD architecture and compact timing control modules based on a field programmable gate array (FPGA), we achieved long term stable operation of a 1x64 QKD network system. Using this architecture, 64 users can simultaneously share secret keys with one server, without using complex software algorithms and expensive hardware. We demonstrated the working of a 1x4 QKD network system using the fiber network of a metropolitan area.
