Optical quantum memory and its applications in quantum communication systems



Lijun Ma, Xiao Tang, Oliver T. Slattery


Optical quantum memory is a device that can store the quantum state of photons and retrieve it with high fidelity on demand. The device can be used to enhance performance for many quantum communication systems such as measurement device independent (MDI) quantum key distribution (QKD). Optical quantum memory is also a critical device to implement quantum repeaters that can break the distance limitation of quantum communication systems and realize long distance QKD. This chapter provides a general overview of the theory and experimental results of optical quantum memory, and discusses its applications in quantum communication systems to date.
