We examine the entanglement of two atoms induced by an external quantum system. Both two-level atoms are coupled to a third two-level system by dipole interaction, and the third system is under the influence of a certain environment. We examine different types of environments and show that the steady-state bipartite entanglement can be achieved. We show that a strongly fluctuating environment is more preferable because the transmission of quantum fluctuations to the atomic system creates and supports steady-state entanglement with a higher amount of concurrence than a nonfluctuating environment or an environment with strong classical fluctuations.
