Experimental quantification of non-gaussianity of phase-randomized coherent states / A. Allevi, S. Olivares, M. Bondani. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 10:8(2012), pp. 1241006.1-1241006.9. [10.1142/S0219749912410067]
Abstract:
We present the experimental investigation of the non-Gaussian nature of some mixtures of Fock states by reconstructing their Wigner function and exploiting two recently introduced measures of non-Gaussianity. In particular, we demonstrate the consistency between the different approaches and the monotonicity of the two measures for states belonging to the class of phase-randomized coherent states. Moreover, we prove that the exact behavior of one measure with respect to the other depends on the states under investigation and devise possible criteria to discriminate which measure is more useful for the characterization of the states in realistic applications. © 2012 World Scientific Publishing Company.
