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.

Abstract:

The generation of entanglement through global phase functions was studied. Necessary and sufficient conditions for the application of global phases to the pure product state to result in entanglement were obtained. The maximum entanglement creation by global phases was considered as well as its corresponding examples.
