Remote information concentration using a bound entangled state

Remote information concentration, the reverse process of quantum teleclonin g, is presented. In this scheme, quantum information originally from a sing le qubit. but now distributed into three spatially separated qubits, is rem otely concentrated back to a single qubit via an initially shared entangled state without performing any global operations. This entangled state is a single unlockable bound entangled slate and we analyze its properties.
