| 摘 要： | 提出在外加强经典场的非共振热腔中制备两个与腔场的耦合系数不同的级联三能级原子最大纠缠态的方法．因外加强经典场的存在，有效哈密顿中与光子数有关的部分被取消．此方法的优点在于腔场可以处于任意态。

| Abstract: | We propose a scheme to prepare a maximally entangled state of two ladder-type three-level atoms with have difference coupling constant with a non-resonant thermal cavity and driven by the external strong classical flied. Because of the external driven strong classical flied, the photon-number-dependent parts in the effective Hamiltonian are canceled. The advantage of scheme is that the cavity may be in any state. |
