Complex amplification and non-symmetric amplitude damping of two-mode Gaussian state
Li-xhen Jiang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
The evolution of two-mode Gaussian state under complex amplification, non-symmetric damping and thermal noise is studied. The analytical time dependent solution of the state characteristic function is obtained in some special cases. The separability criterions are given for the final state of weak complex amplification as well as strong complex amplification.
