摘要：

We propose a scheme of entanglement purification via entanglement swapping. The scheme needs less classical communication to achieve the optimal purifying. We also prove that the optimal success probability is equal to the smaller entanglement of a single pair purification of these two pairs. (C) 2002 Elsevier Science B.V. All rights reserved.
