Optical quantum memory is a device that can store the quantum state of photons andretrieve it on demand and with high fidelity. It is emerging as an essential device toenhance security, speed, scalability, and performance of many quantum systems used incommunications, computing, metrology, and more. In this paper, we will specificallyconsider the impact of optical quantum memory on quantum communications systems.Following a general overview of the theoretical and experimental research progress inoptical quantum memory, we will outline its role in quantum communications, including asa photon source, photon interference, quantum key distribution (QKD), quantumteleportation, quantum repeater, and quantum networks.
