Query: Generalized protocol for distribution and concentration of Quantum
  information   Alice can distribute a quantum state $|\phi>$ to $N$ 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.
