Creation of cluster coherent states in cavity QED

Abstract

Abstract: 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 Λ type atom driven by two classical fields and two bimodal cavities, we can ignore the spontaneous emission of the atom. 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.

Key words: quantum optics, cluster state, entangled coherent state, bimodal cavity, cavity QED
