Title: Continuous-variable quantum-information distributor: Reversible telecloning

Abstract

We first classify the quantum clone into irreversible and reversible types from the perspective of quantum-information distribution. We propose a scheme of continuous-variable reversible telecloning, which broadcast the information of an unknown state without loss from a sender to several spatially separated receivers exploiting multipartite entanglement as quantum channels. In this scheme, the quantum information of an unknown state is distributed into M optimal clones and M-1 anticlones using 2M-partite entanglement. For the perfect quantum-information distribution that is optimal cloning, 2M-partite entanglement is required to be a maximum two-party entanglement.
