In the original one-to-one teleportation protocol of Bennett et al. , an observer, Alice, transmits the information of a d-level system to another observer, Bob, with perfect fidelity, by using a maximally entangled state. We introduce a generalization called the many-to-many teleportation, where the information is sent from N observers to M receivers situated at different locations. One of the most interesting applications of quantum cloning is the symmetric broadcasting of entanglement proposed by Buzek et al. . We propose the splitting of entanglement based on a local optimal universal asymmetric cloning machine and, then, by applying the Peres-Horodecki criterion, we analyze the inseparability of the final states.
