Optical Quantum Memory Applications In Quantum Communication

Optical quantum memory is a device that can store the quantum state of photons and retrieve it with high fidelity on demand. Many approaches to quantum memory have been proposed and demonstrated. Quantum memory can be used to enhance performance in many quantum communication systems and processes such as deterministic single photon sources, photon interference, measurement device independent (MDI) quantum key distribution (QKD), quantum teleportation and quantum repeaters.
