11 Jan 2020 Abbasli N. Abgaryan V. Bures M. Khvedelidze A. Rogojin I. Torosyan A.

In the present report we discuss measures of classicality/quantumness of states of finite-dimensional quantum systems, which are based on a deviation of quasiprobability distributions from true statistical distributions. Particularly, the dependence of the global indicator of classicality on the assigned geometry of a quantum state space is analysed for a whole family of Wigner quasiprobability representations...
