纠缠相干态的制备
Entangled coherent states: generation
摘要
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 isproposed.Discussions on the two ECSs are presented.When the atom interacts separately with two Ramsey zones and two cavity modes,the generation of Bell-type ECSs in separate cavities is realized after an atomic measurement.By adding the Ramsey zones and cavity modes,the cluster-type ECSs can be generated.The interaction time between the atom and cavity modes are all π/2λ,where λ is the effective atom-cavity coupling constant.At last the experimental feasibility of such proposal is discussed.关键词
