Following a recent scheme by Zheng and Guo,we propose protocols for the generation of three-atom W class of maximally entangled state and an interesting quantum state,which is also the maximally two- at-om entangled state.These are based on the simultaneous interaction of three atoms with a single- mode cavityfield.Unlike previous scheme,the cavity field in our scheme is initially in thermal states with n photons.Finally,suggestion for experimental probability is given.%提出了制备三原子W态和一个处于最大纠缠的两原子态的方案,这些均基于三个原子同时与单模腔场相互作用实现的.与郑郭方案不同,本方案的腔场初始处于n光子的热态,因而具有更大的现实意义.最后分析了该方案在实验上实现的可行性.
