Quantum teleportation of entangled coherent states - art. no. 022302

We propose a simple scheme for the quantum teleportation of both bipartite and multipartite entangled coherent states with the success probability 1/2 . The scheme is based only on linear optical devices such as beam splitters and phase shifters, and two-mode photon number measurements. The quantum c hannels described by the multipartite maximally entangled coherent states, are readily made by the beam splitters and phase shifters.
