摘　　要：本文提出了一个基于腔QED技术的制备三原子最大W态的一般方案。通过讨论表明三个原子不论是被同时注入腔中还是在不同的时刻被注入腔中我们都能得到三原子最大W态。A general scheme of preparing three-atom maximally W state is proposed. Our proposal is based on cavity QED. The discussion of this scheme indicates we can obtain three-atom maximally W state whether the atoms are injected into the cavity simultaneously or at different time. It can be realized by current technologies and it also can be generalized to prepare the n-atom W states.
