Remote information concentration using a bound entangled state.

Phys Rev Lett 86:2 (2001) 352-355

Authors:

M Murao, V Vedral

Abstract:

Remote information concentration, the reverse process of quantum telecloning, is presented. In this scheme, quantum information originally from a single qubit, but now distributed into three spatially separated qubits, is remotely 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 state and we analyze its properties.
