Optical photons are powerful carriers of quantum information, which can be delivered in free space by satellites or fibers on the ground over long distances. Entanglement states distances empower computing, communications, and sensing. Quantum optical memories effectively store manipulate states, makes them indispensable elements future long-distance networks. Over past two decades, with high fidelity, efficiencies, storage times, promising multiplexing capabilities have been developed, especially at single photon level. In this review, we introduce working principles commonly used memory protocols summarize recent advances demonstrations. We also offer a vision for devices that may enable entanglement distribution
