利用纠缠交换制备原子-原子最大纠缠态
The scheme for generating maximally entangled atom-atom states via entanglement swapping
摘要
Abstract
A relatively simple scheme for the generation of maximally entangled atom-atom state is proposed,which is based on two entangled (Ⅲ)-type three-level atom-cavity systems using techniques of cavity quantum electrodynamics(QED).Initially,there is no entanglement between the two atoms,nor between the two cavity fields,and then one atom interacts with a cavity field.The scheme only requires measuring a single cavity state and precisely control the evolution time,so as to occur the entanglement of two atoms without previous interac-tion.More specially,the scheme can considerably prolong the effective leakage time of the cavity and overcome the decoherence effect of the cavity,thus the requirements of system on the quality of the cavity are greatly loos-ened.Numerical simulation results show that maximally entangled states with high fidelity can be obtained by precisely controlling the evolution time.关键词
