Abstract
We consider the time evolution of the tripartite three mode Gaussian state which is initially prepared in genuine entangled pure state. The state undergoes parametric amplification and amplitude damping as well as thermal noise. The correlation matrix of the evolved state is studied in the symmetrical case. The separability conditions are given.
