Manipulating the non-Gaussianity of phase-randomized coherent states / A. Allevi, S. Olivares, M. Bondani. - In: OPTICS EXPRESS. - ISSN 1094-4087. - 20:22(2012), pp. 24850-24855. [10.1364/OE.20.024850]
Abstract:
We experimentally investigate the non-Gaussian features of the phase-randomized coherent states, a class of states exploited in communication channels and in decoy state-based quantum key distribution protocols. In particular, we reconstruct their phase-insensitive Wigner functions and quantify their non-Gaussianity. The measurements are performed in the mesoscopic photon-number domain by means of a direct detection scheme involving linear detectors. © 2012 Optical Society of America.
