Teleportation of a bipartite entangled coherent state via cavity QED
Zhou Yan-Li, Hong‐Yi Dai, Yang Li-Jia · Chinese Physics · 2007
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.
