We microscopically model the decoherence dynamics of entangled coherent states of twooptical modes under the influence of vacuum fluctuation. We derive an exact masterequation with time-dependent coefficients reflecting the memory effect of the environ-ment, by using the Feynman-Vernon influence functional theory in the coherent-state rep-resentation. Under the Markov approximation, our master equation recovers the widelyused Lindblad equation in quantum optics. We then investigate the non-Markovianentanglement dynamics of the two-mode entangled coherent states under vacuum fluc-tuation. Compared with the results in Markov limit, it shows that the non-Markovianeffect enhances the disentanglement to the initially entangled coherent state. Our anal-ysis also shows that the decoherence behaviors of the entangled coherent states dependon the symmetrical properties of the entangled coherent states as well as the couplingsbetween the optical fields and the environment. |
