We investigate how the density operator of a squeezed chaotic field (a mixed state) evolves in the amplitude dissipative channel. We demonstrate that the evolved density operator ρ(t) is in a Gaussian quadratic form, and the Q-function of ρ(t) is derived, which manifestly exhibits the dissipation.

Keywords:Quantum dissipation;IWOP;Q-function
