压缩混态在振幅耗散通道的演化
Evolution of squeezed chaotic state in an amplitude dissipative channel
我们研究了压缩噪声场（混态）的密度算符在振幅耗散通道如何演化。我们还证明了演化密度算符ρ(t)处于高斯二次态型，同时给出了相应地反映通道耗散特性的Q函数。
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.
