论文摘要
量子网络已被证明可将用户与没有信任节点的全网拓扑连接。我们介绍了基于可扩展的极化基于纠缠的量子网络测试床的进步，该测试能够执行超出简单量子密钥分布的协议。我们的方法利用了波长多路复用，这是整个本地大都市区域的量子网络的理想选择，这是因为可以轻松将其他用户连接到网络而不增加每个用户的资源需求。我们显示了一个具有大都市量表的10个用户完全连接的量子网络，该网络已部署了光纤链接，表明了极化稳定性以及在10.8天内生成秘密键的能力，网络较大的平均秘密密钥率为3.38 bps。
Quantum networks have been shown to connect users with full-mesh topologies without trusted nodes. We present advancements on our scalable polarisation entanglement-based quantum network testbed, which has the ability to perform protocols beyond simple quantum key distribution. Our approach utilises wavelength multiplexing, which is ideal for quantum networks across local metropolitan areas due to the ease of connecting additional users to the network without increasing the resource requirements per user. We show a 10 user fully connected quantum network with metropolitan scale deployed fibre links, demonstrating polarisation stability and the ability to generate secret keys over a period of 10.8 days with a network wide average-effective secret key rate of 3.38 bps.
