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