We investigate the entanglement dynamics of two space-separated atoms, one of them in Jaynes–Cummings cavity and the other isolated completely. We show analytically that initial entanglement has an interesting subsequent time evolution and transfer, including the so-called sudden death effect. A little inconsistency of concurrence and negativity is indicated qualitatively to measure the two-qubit states.
