Homodyne-like detection for coherent state-discrimination in the presence of phase noise / M. Bina, A. Allevi, M. Bondani, S. Olivares. - In: OPTICS EXPRESS. - ISSN 1094-4087. - 25:9(2017), pp. 10685-10692. [10.1364/OE.25.010685]
Abstract:
We propose a homodyne-like detection scheme involving photon-number-resolving detectors to discriminate between two coherent states affected by either uniform or gaussian phase noise. A proof-of-principle experiment is performed employing two hybrid photodetectors, whose outputs are used in post processing to calculate the shot-by-shot photon-number differences. The performance of the strategy is quantified in terms of the error probability in discriminating the noisy coherent signals as a function of the characteristic noise parameters.
