Generalizing Stratonovich-Weyl axioms for composite systems
Arsen Khvedelidze
The statistical model of quantum mechanics is based on the mapping between operators on the Hilbert space and functions on the phase space. This map can be implemented by an operat…
Parameterizing Qudit States
Arsen Khvedelidze, Dimitar Mladenov, Astghik Torosyan
Quantum systems with a finite number of states at all times have been a primary element of many physical models in nuclear and elementary particle physics, as well as in condensed…
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…
The global indicator of classicality of an arbitrary -level quantum system
Vahagn Abgaryan, Arsen Khvedelidze, Astghik Torosyan
It is commonly accepted that a deviation of the Wigner quasiprobability distribution of a quantum state from a proper statistical distribution signifies its nonclassicality. Follow…
On moduli space of the Wigner quasiprobability distributions for -dimensional quantum systems
Vahagn Abgaryan, Arsen Khvedelidze, Astghik Torosyan
A mapping between operators on the Hilbert space of -dimensional quantum system and the Wigner quasiprobability distributions defined on the symplectic flag manifold is discusse…
