论文摘要
量子通信是由于理论上证明的量子力学安全性而开发的，量子力学的安全性可能成为未来信息安全的主要技术。但是，大多数研究和实施仅限于两个或几个政党。本文中，我们为大量用户提供了一个完全连接的量子通信网络，而没有受信任的节点。使用灵活的波长弹性/多路复用和空间多路复用技术，由40个用户同时连接，而无需通过可信的节点与宽带能量时纠缠的光子对源相连。由于其简单性，可扩展性和高效率，该网络架构可以广泛部署在公司，学校和社区等实际场景中。
Quantum communication is developed owing to the theoretically proven security of quantum mechanics, which may become the main technique in future information security. However, most studies and implementations are limited to two or several parties. Herein, we propose a fully connected quantum communication network without a trusted node for a large number of users. Using flexible wavelength demultiplex/multiplex and space multiplex technologies, 40 users are fully connected simultaneously without a trusted node by a broadband energy-time entangled photon pair source. This network architecture may be widely deployed in real scenarios such as companies, schools, and communities owing to its simplicity, scalability, and high efficiency.
