Displacement Controlled Photon Number Resolving Detector for Coherent State Discrimination
Christoffer Wittmann, Ulrik L. Andersen, Masahiro Takeoka, Сыч Денис Васильевич, Gerd Leuchs · 2010
The presented probabilistic scheme for discrimination of optical coherent states consists of an optimized displacement followed by postselection of a photon number resolving measurement. The scheme outperforms the homodyne receiver in theory and experiment.
