Extreme non-negative Wigner functions
Zacharie Van Herstraeten, Jack Davis, Nuno C. Dias +3
Providing an operational characterization of the Wigner-positive states (WPS), i.e., the set of quantum states with non-negative Wigner function, is a longstanding open problem. Fo…

Characterising the sets of quantum states with non-negative Wigner function
Nicolas J. Cerf, Ulysse Chabaud, Jack Davis +3
For Hilbert spaces we consider the convex sets of Wigner-positive states (WPS), i.e.~density matrices over $\mathcal…

Wigner entropy conjecture and the interference formula in quantum phase space
Zacharie Van Herstraeten, Nicolas J. Cerf
Wigner-positive quantum states have the peculiarity to admit a Wigner function that is a genuine probability distribution over phase space. The Shannon differential entropy of the…
