Title: Decoherence and disentanglement for two qubits in a common squeezed reservoir
Abstract: We study the relation between the sudden death and revival of the entanglement of two qubits in a common squeezed bath and the decoherence. By getting ``close'' to the decoherence free subspace, we show that the death time shows a decrease and subsequent increase until the sudden death disappears and the concurrence goes to its steady-state value asymptotically.
