Abstract
The finite-Time disentanglement Via spontaneous emission is discussed. The two entangled qubits become completely disentangled in a finite-time under the influence of pure vacuum noise. The two-level atoms A and B were coupled indivisually to two cavities which are initially in the vacuum states. The result show that for the physically fundamental and unavoidable process of spontaneous emisson that nonlocal entanglement times are shorter than local decoherence times for arbitrary entangled state either pure or mixed.
