论文摘要
量子密钥分布（QKD）网络有望在多方共享安全的随机性。大多数现有的QKD网络方案和演示基于可信赖的继电器或限于点对点方案。在这里，我们提出了一个灵活且可扩展的方案，称为开放式末端测量设备无关的QKD网络。该计划对不受信任的继电器和所有检测器侧通道攻击享有安全性。特别是，任何用户都可以在网络中其他人的帮助下完成关键分布。作为例证，我们详细说明了一个四用户网络，其中两个用户通过考虑到来源和检测器的缺陷来建立安全的通信并进行逼真的模拟。
Quantum key distribution (QKD) networks hold promise for sharing secure randomness over multi-partities. Most existing QKD network schemes and demonstrations are based on trusted relays or limited to point-to-point scenario. Here, we propose a flexible and extensible scheme named as open-destination measurement-device-independent QKD network. The scheme enjoys security against untrusted relays and all detector side-channel attacks. Particularly, any users can accomplish key distribution under assistance of others in the network. As an illustration, we show in detail a four-user network where two users establish secure communication and present realistic simulations by taking into account imperfections of both sources and detectors.
