    "abstract": "Alice can distribute a quantum state $|\\phi\u003e$ to $N$ spatially separated\nparties(say Bobs) by telecloning. It is possible for Charlie to reconstruct the\nquantum state to him if he shares same kind of telecloning quantum channel with\nBobs using only LOCC. For N=3 reconstruction can be done faithfully using\nSmolin\u0027s 4 party unlockable bound entangled state as shared channel. In this\nnote we investigate, in multiparty setting, the general structure of quantum\nchannel and protocol by which faithful distribution and concentration of\nquantum information can be done.",
