摘要
提出一个在腔QED中产生cluster-型纠缠相干态的方案。基于三能级A型原子和双模腔场之间的大失谐相互作用,原子的自发辐射可以忽略。此外,腔场的初态是真空态。在这个方案中,对原子进行测量后,能够产生腔场cluster-型纠缠相干态,并讨论了实验的可行性。
A scheme is proposed for the creation of cluster-type entangled coherent states via cavity QED. Based on the large detuning condition interaction between a three-level A type atom driven by two classical fields and two bimodal cavities, the spontaneous emission of the atom can be ignored. Moreover, the initial states of the two cavity fields are all prepared in vacuum. In this scheme, it is shown that the cluster-type entangled coherent states can be generated after the atomic measurement, and the experimental feasibility is also discussed.
