    "abstract": "We propose a scheme of continuous-variable reversible telecloning, which\nbroadcast the information of an unknown state without loss from a sender to\nseveral spatially separated receivers exploiting multipartite entanglement as\nquantum channels. In this scheme, quantum information of an unknown state is\ndistributed into $M$ optimal clones and $M-1$ anticlones using $2M$% -partite\nentanglement. For the perfect quantum information distribution that is optimal\ncloning, $2M$-partite entanglement is required to be a maximum two-party\nentanglement. Comparing with the quantum telecloning proposed by Loock and\nBraunstein [Phys. Rev. Lett. 87, 247901 (2001)], this protocol produces the\nanticlones (or time-reversed state) of the unknown quantum state, thus, keep\nall information of an unknown state.",
