摘要：

Decoherence of two atoms initially prepared in Bell states in free space is discussed theoretically through calculation of the probabilities for the atoms to remain respectively in these states. It is found that, due to quantum interference, the atoms never follow a purely exponential law to decohere from their initial states, even though spontaneous emission is illustrated to cause the decoherence.
