    "abstract": "Quantum state discrimination for two coherent states with opposite phases as\nmeasured relative to a reference pulse is analyzed as functions of the\nintensities of both the signal states and of the reference pulse. This problem\nis relevant for Quantum Key Distribution with phase encoding. We consider both\nthe optimum measurements and simple measurements that require only\nbeamsplitters and photodetectors.",
