On the stratifications of 2-qubits X-state space
Arsen Khvedelidze, Astghik Torosyan
The 7-dimensional family of so-called mixed X-states of 2-qubits is considered. Two types of stratification of 2-qubits state space, i.e., partitions of $\math…

On the family of Wigner functions for N-level quantum system
Arsen Khvedelidze, Vahagn Abgaryan
The family of unitary non-equivalent Weyl-Stratonovich kernels determining the Wigner probability distribution function of an arbitrary N-level quantum system is constructed.
