摘要:

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中或在地面光纤中实现长距离传输。量子态在长距离上的纠缠可以赋能量子计算、量子通信和量子感知。量子光学存储器能够有效地存储和操控量子态,这使其成为未来长距离量子网络中不可或缺的要素。在过去二十年中,尤其是在单光子水平上,已经发展出具有高保真度、高效率、长存储时间以及良好复用能力的量子光学存储器。在这篇综述中,我们介绍了常用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。我们还对未来的量子光学存储器件提出了展望,这些器件可能实现长距离纠缠分发。

英文摘要:

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.
