The phase‐space formulation of quantum mechanics has recently seen increased use in
testing quantum technologies, including methods of tomography for state verification and …

In this study, we determine a violation of the Leggett-Garg inequalities due to gravitational
interaction in a hybrid system consisting of a harmonic oscillator and a spatially localized …

Generating macroscopic nonclassical quantum states is a long-standing challenge in
physics. Anharmonic dynamics is an essential ingredient to generate these states, but for …

Quantum system attributes, notably entanglement, are indispensable in manipulating
quantum information tasks. Ergo, machine learning applications to help harness the …

The Moyal equation for the Wigner function was obtained under the assumption that the
potential is an analytic function. The polynomial form of the potential is a natural …

In this paper, a novel scheme for bidirectional and asymmetric controlled quantum
teleportation in the three-dimensional system via a nine-qutrit entangled state as the …

The nonclassicality of simple spin systems as measured by Wigner negativity is studied on a
spherical phase space. Several SU (2)-covariant states with common qubit representations …

This paper investigates the behaviour of the quantum correlations for an accelerated two-

The concept of quantum‐mechanical nematic order, which is important in systems such as
superconductors, is based on an analogy to classical liquid crystals, where order …

In this work we construct Wigner functions for hybrid continuous and discrete variable
quantum systems. We demonstrate new capabilities in the visualization of the interactions …
