    "abstract": "We give out the time evolution solution of simultaneous amplitude and phase\ndamping for any continuous variable state. For the simultaneous amplitude and\nphase damping of a wide class of two- mode entangled Gaussian states, two\nanalytical conditions of the separability are given. One is the sufficient\ncondition of separability. The other is the condition of PPT separability where\nthe Peres-Horodecki criterion is applied. Between the two conditions there may\nexist bound entanglement. The simplest example is the simultaneous amplitude\nand phase damping of a two-mode squeezed vacuum state. The damped state is\nnon-Gaussian.",
