摘要：

The dynamics of the entanglement rate are investigated in this Letter for pairwise interaction and two special sets of initial states. The results show that for the given interaction and the decoherence scheme, the competitions between decohering and entangling lead to two different results-some initial states may be used to prepare entanglement while the others do not. A criterion on decohering and entangling is also presented and discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
