Entangled coherent states: generation

Abstract

Abstract:

A scheme of generating the Bell-type and cluster-type entangled coherent states (ECSs) via a single two-level atom and cavity modes initially prepared in coherent states is proposed. Some discussions on the two ECSs are presented. When the atom interacts separately with two Remsey zones and two cavity modes, the generation of Bell-type ECSs in separate cavities is realized after an atomic measurement. By adding the Remsey zones and cavity modes, the cluster-type ECSs can be generated. The interaction time between the atom and cavity modes are all Π/λ, where λ is the effective atom-cavity coupling constant. At last the experimental feasibility of such proposal is discussed.

Key words: quantum optics, quantum entanglement, coherent states, cavity QED
