Abstract:
In the original work of Bennett et al., quantum teleportation of the information contained in a d-level system was introduced. In this scheme, an observer Alice transmits the information of the particle to another observer Bob with perfect fidelity, by using a maximally entangled state.
We propose a generalization of teleportation, namely, the many-to-many quantum transmission of the information of a d-level system from N senders spatially separated to M receivers (M>N). In this new scheme, the unknown state to be teleported is an entangled N-particle state shared by N observers.
