Generalized protocol for distribution and concentration of Quantum information

Quantum Physics 2007-05-23 v1

Abstract

Alice can distribute a quantum state ϕ>|\phi> to NN spatially separated parties(say Bobs) by telecloning. It is possible for Charlie to reconstruct the quantum state to him if he shares same kind of telecloning quantum channel with Bobs using only LOCC. For N=3 reconstruction can be done faithfully using Smolin's 4 party unlockable bound entangled state as shared channel. In this note we investigate, in multiparty setting, the general structure of quantum channel and protocol by which faithful distribution and concentration of quantum information can be done.
