| 摘 要： | Based on the atom-cavity-field interaction, this paper proposes a scheme for the teleportation of a bipartite entangled coherent state （ECS） with high fidelity as long as │α│ is not too small. In this proposal, only four cavities and a three-level cascade atom are needed. The fidelity of the ECS is calculated and analysed in detail.

| Abstract: | Based on the atom--cavity--field interaction, this paper proposes a
scheme for the teleportation of a bipartite entangled coherent state
(ECS) with high fidelity as long as $\left| \alpha \right|$ is not
too small. In this proposal, only four cavities and a three-level
cascade atom are needed. The fidelity of the ECS is calculated and
analysed in detail. |
