We present a phenomenon of an asymptotic revival of bipartite entanglement between two stable solid-state qubits interacting via a single-mode cavity subject to dissipation. This effect is achievable in cavity quantum electrodynamics systems, assisted with strong classical pumping detuned from the cavity eigenmode, under the assumption of short system-bosonic reservoir correlation times. Moreover, we prove that this effect is independent of the initial cavity state and that all initially prepared Bell states experience the same qualitative effects. We present a method that can be used to generalize an arbitrary number of solid-state qubits.
