Wigner distribution function for Euclidean systems

Luis Miguel Nieto, Natig M. Atakishiyev, S. M. Chumakov +1 more

Euclidean systems include poly- and monochromatic wide-angle optics, acoustics, and also infinite discrete data sets. We use a recently defined Wigner operator and (quasiprobability) distribution function to set up and study the phase-space evolution of these models, subject to differential and difference equations, respectively. Infinite data sets and two-dimensional monochromatic (Helmholtz) fields are thus shown by their Wigner function on a cylinder of direction and location; the Wigner function for polychromatic wavefields has ` c -number' coordinates of (two-dimensional) wavenumber and position.Euclidean systems include poly- and monochromatic wide-angle optics, acoustics, and also infinite discrete data sets.

On Measures of Classicality/Quantumness in Quasiprobability Representations of Finite-Dimensional Quantum Systems

N. Abbasli, V. Abgaryan, M. Bures +3 more

Abstract 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. General considerations are exemplified by constructing the global indicator of classicality/quantumness for the Hilbert–Schmidt, Bures and Bogoliubov–Kubo–Mori ensembles of qubits and qutrits.Abstract 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.
