Kenfack Zyczkowski indicator of nonclassicality for two non-equivalent representations of Wigner function of qutrit
Vahagn Abgaryan, Arsen Khvedelidze, Astghik Torosyan
The Wigner function of a finite-dimensional system can be constructed via dual pairing of a density matrix with the Stratonovich-Weyl kernel. Following Kenfack and …

On measures of classicality/quantumness in quasiprobability representations of finite-dimensional quantum systems
N. Abbasli, V. Abgaryan, M. Bures +3
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 distributi…
