基于腔QED制备W纠缠态
Scheme for preparation of W state in cavity QED
摘要
Abstract
We propose a scheme to generate two-photon four-particle W state with maximized fidelities by means of nonresonant interaction between one three-level Rydberg atom and four cavities via two-photon process. The scheme requires the four cavities initially prepared in the vacuum state and the atom in the excited state. We ob-tain desired W state by choosing proper the atom-field interaction time. Numerical calculation demonstrates that our scheme is experimentally feasible and has higher fidelity.关键词
