Entanglement purification with two-way classical communication
Alan W. Leung, Peter W. Shor
abstract: We present an improved protocol for entanglement purification of bipartite
mixed states. The protocol requires two-way classical communication and hence
implies an improved lower bound on the quantum capacity with two-way classical
communication of the quantum depolarizing channel.
