Abstract : This effort was primarily concerned with quantum aspects of optical communications. Two quantum communications technologies were studied: (1) Vulnerabilities in coherent state quantum data encryption, and (2) Quantum operations on entangled photon pairs using Lyot filters. Both operations enjoy security due to an eavesdroppers measurement disadvantage with respect to authorized users. This insures the authorized users enjoy an information advantage over the eavesdropper when measuring the quantum states, be they coherent state quantum data encryption or entangled photon pair quantum key distribution.
