Influence of phase damping on the entanglement for the damped JC model in the pure and mixed states
A.‐S. F. Obada, H. A. Hessian, A.‐B. A. Mohamed
In this article, we investigate the effects of phase damping on the temporal evolution of different entanglement measurements and the amount of entanglement for the damped Jaynes-Cummings model. The master equation is solved for any initial state in the two-level atom. Superpositions of two coherent states (π/2 or π out of phase) and their statistical mixture state are taken as initial states when a phase-damped cavity is taken into account.
