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.

EXPERIMENTAL QUANTIFICATION OF NON-GAUSSIANITY OF PHASE-RANDOMIZED COHERENT STATES

TLDR
It is proved that the exact behavior of one measure with respect to the other depends on the states under investigation and possible criteria to discriminate which measure is more useful for the characterization of the states in realistic applications are devised.

TLDR
The generation and characterization of the class of bracket states, namely phase-sensitive mixtures of coherent states exhibiting symmetry properties in the phase-space description, and the possibility to exploit this dependence to monitor the phase difference for the enhancement of the performances of a simple communication scheme based on direct detection are presented.

TLDR
The reconstruction of the quantum state of light from the homodyne photocounting statistics of a single, realistic photodetector is proposed and it is shown that perturbing effects due to classical noise of the local oscillator are small.

This method allows a simple passive preparation of decoy states for quantum key distribution, and it is shown that the resulting key rates are comparable with the performance of active choices of intensities of Poissonian signals.
