摘要：

We present an entanglement purification protocol based on controlled-controlled-NOT operations and Bell state measurements. We show that the protocol is more efficient than the standard protocol of Bennett et al. [Phys. Rev. Lett. 76 (1996) 722]. (C) 2000 Elsevier Science B.V. All rights reserved.
