摘　　要：研究在热腔场中制备Ξ型三能级原子最大纠缠态的方案.利用多个全同三能级原子同时和一个单模腔场的大失谐相互作用来制备三能级原子最大纠缠态,可忽略腔场热作用和腔延迟作用的影响.文中还研究在热腔场中制备四能级原子最大纠缠态的方案.A scheme for preparation of the maximal entangled states for Ξ-type three-level atoms in a thermal cavity is proposed. Because of preparing the maximal entangled states by the simultaneous nonresonant interaction between many uniform multilevel atoms and a single-mode cavity, the thermal effects and the decay of the cavity are all eliminated. It also suggests a scheme for preparation of the maximal entangled states for four-level atoms in a thermal cavity.

关 键 词：三粒子W态 最大纠缠态 大失谐相互作用
