# Manipulating the non-Gaussianity of phase-randomized coherent states.

@article{Allevi2012ManipulatingTN, title={Manipulating the non-Gaussianity of phase-randomized coherent states.}, author={Alessia Allevi and Stefano Olivares and Maria Bondani}, journal={Optics express}, year={2012}, volume={20 22}, pages={ 24850-5 } }

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.
