光学光子是量子信息的强大载体，可以通过卫星在自由空间传输，也可以通过地面光纤远距离传输。远距离量子态的纠缠可以为量子计算、量子通信和量子传感提供动力。量子光学存储器可以有效地存储和操纵量子态，这使得它们成为未来远距离量子网络中不可或缺的元素。在过去的二十年里，量子光学存储器已经被开发出来，它具有高保真、高效率、长存储时间和良好的多路复用能力，特别是在单光子水平上。在这篇综述中，我们介绍了常用的量子存储协议的工作原理，并总结了量子存储演示的最新进展。我们还展望了未来量子光学存储器件的前景，这种器件可能会实现长距离的纠缠分布。
Optical photons are powerful carriers of quantum information, which can be delivered in free space by satellites or in fibers on the ground over long distances. Entanglement of quantum states over long distances can empower quantum computing, quantum communications, and quantum sensing. Quantum optical memories can effectively store and manipulate quantum states, which makes them indispensable elements in future long-distance quantum networks. Over the past two decades, quantum optical memories with high fidelity, high efficiencies, long storage times, and promising multiplexing capabilities have been developed, especially at the single photon level. In this review, we introduce the working principles of commonly used quantum memory protocols and summarize the recent advances in quantum memory demonstrations. We also offer a vision for future quantum optical memory devices that may enable entanglement distribution over long distances.
