Evolution of Wigner functions as a function of β = x + iy (x,y ∈ [−5,5]) for PATS in thermal-loss channel with fixed ne = 0, ns = 0 and (a) m = 1, (b) m = 2, and (c) m = 3 at different time κt = 0 (column 1), 0.25 (column 2), and 2 (column 3). Indeed, this corresponds to the evolution of Fock state in loss channel.
