Abstract
Systems and methods are described in which both a quantum key distribution (QKD) transmitter and QKD receiver may keep both of their two-path interferometers stable, with regard to path length drift, relative to an internal reference laser are described. Systems and methods are also proposed whereby the transmitter interferometer may have only a single path (e.g., Sagnac interferometers). The systems and methods described herein may greatly improve the performance of quantum cryptographic transceivers that may make use of these systems and methods.
