Demonstration of near-Optimal Discrimination of Optical Coherent States
arXiv:0809.4953 · doi:10.1103/PhysRevLett.101.210501
Abstract
The optimal discrimination of non-orthogonal quantum states with minimum error probability is a fundamental task in quantum measurement theory as well as an important primitive in optical communication. In this work, we propose and experimentally realize a new and simple quantum measurement strategy capable of discriminating two coherent states with smaller error probabilities than can be obtained using the standard measurement devices; the Kennedy receiver and the homodyne receiver.
