WebMar 30, 2024 · The Wigner function is a phase space description, so it is well suited for looking at continuous degrees of freedom. If you consider an optical Schrödinger cat state to be entangled, the Wigner function would be a good way to look at it. However, if you really want to have a look at pair states, you need correlations between different modes ... WebOct 1, 2014 · Abstract and Figures. Photon-number-resolving (PNR) detection allows for the direct measurement of the Wigner quasi-probability distribution of an optical mode without the need for numerically ... WebMar 7, 2007 · We discuss nonclassical properties of single-photon subtracted squeezed vacuum states in terms of the sub-Poissonian statistics and the negativity of the Wigner function. We derive a compact expression for the Wigner function from which we find the region of phase space where Wigner function is negative. We find an upper bound on the … bit of life game
