On the Nonclassicality Distance Indicator of Qudits : [Abstract] / A.Khvedelidze, A.Torosyan // Физика элементарных частиц и атомного ядра. – 2024. – Т. 55, № 3. – P. 703. – URL: http://www1.jinr.ru/Pepan/v-55-3/83_Khvedelidze_ann.pdf.

We consider the nonclassicality distance indicator of a state in finite-dimensional quantum systems which is evaluating a state nonclassicality by its remoteness from the set of “classical states”. The latter are identified with those states whose Wigner function is non-negative. The corresponding Wigner function’s positivity polytope in the simplex of qudit eigenvalues is introduced and the representation for the nonclassicality distance indicator as a piecewise function is derived. The results are exemplified by the qutrit case
