A theoretical model for driving a two qubit system to a stable long-livedentanglement is discussed. The entire system is represented by two atoms,initially in ground states and disentangled, each one coupled to a separatecavity with the cavities connected by a fiber. The cavities and fiber exchangeenergy with their individual thermal environments. Under these conditions, weapply the theory of microscopic master equation developed for the dynamics ofthe open quantum system. Deriving the density operator of the two-qubit systemwe found that stable long-lived quantum correlations are generated in thepresence of thermal excitation of the environments. To the best of ourknowledge, there is no a similar effect observed in a quantum open systemdescribed by a generalized microscopic master equation in the approximation ofthe cavity quantum electrodynamics (CQED).
