论文摘要
成熟的量子互联网的部署构成了寻找足够的建筑块，以在远程量子节点之间进行纠缠分布。理想的系统将在光纤中的传播与量子记忆的光线相结合，并利用现有通信网络，同时具有扩展到网络大小所需的可扩展性。在这里，我们演示了在电信波长处与光子纠结的纤维集成量子记忆。该存储设备基于稀有地掺杂的固体的光纤尾部激光引导，并允许对内存的全纤维稳定地址。使用基于纤维的干涉仪进行纠缠的分析。我们的结果特征是在存储时间和效率方面的综合存储纠缠方面的进步顺序，并构成了使用集成设备向量子网络迈出的重要一步。
The deployment of a fully-fledged quantum internet poses the challenge of finding adequate building-blocks for entanglement distribution between remote quantum nodes. An ideal system would combine propagation in optical fibres with quantum memories for light, leveraging on the existing communication network while featuring the scalability required to extend to network sizes. Here we demonstrate a fiber-integrated quantum memory entangled with a photon at telecommunication wavelength. The storage device is based on a fiber-pigtailed laser written waveguide in a rare-earth doped solid and allows an all-fiber stable adressing of the memory. The analysis of the entanglement is performed using fibre-based interferometers. Our results feature orders of magnitude advances in terms of storage time and efficiency for integrated storage of light-matter entanglement, and constitute a significant step forward towards quantum networks using integrated devices.
