Abstract

High bandwidth requirements for data communications are currently being met by classical coherent communication using multi-level modulation of amplitude and phase of light. Alternatively, down at the level of quantum signals, coherent communication enables establishment of cryptographic keys between two legitimate users, and shows higher key exchange throughput compare to single-photon-based systems. In this work, we will examine the feasibility of full duplex quantum coherent communication, where both the transmitter and the receiver engage in quantum signal recovery as well as secure key generation.
