Wigner quasi-probability distribution: W(x,p) = (1/π)∫⟨x+y|ρ|x−y⟩·e^(−2ipy)dy

Layer 1 — Physicsin the quantum-sensing subtree

Wigner quasi-probability distribution: the phase-space representation of a quantum state. Setup: for a density operator ρ on a mode with canonical (x, p), the Wigner function is defined by a Fourier transform of the off-diagonal…
