Communication with a Superposition of two Coherent States
N. Alioui, C. Bendjaballah · Journal of Optical Communications · 2001
An optical communication system using a source of superpositions of two coherent states and various detection schemes (photon counting, homodyne detection and quantum detection) is studied. The results are analyzed and compared with those for a mixture of two coherent states. The merits of superpositions of states for communication purposes are discussed.
