Abstract
We propose a quantum teleportation scheme for tripartite entangled coherent state (ECS) in continuous variable by adopting disentanglement method. Our scheme is feasible and economical in the sense that we only need linear optical devices such as beam splitters, phase shifters and photo detectors and employ bipartite maximally ECS as quantum channel. We also generalize the tripartite scheme into multipartite case and calculate the minimum average fidelity for the schemes in tripartite and multipartite cases.
