我们提出了一个简单的方法产生N个囚禁离子的GHZ态.在这个方法中,初始时处于相同态的N个两能级离子被囚禁在一个线性阱中,同时被两束均匀的经典激光照射.这个方法对振动模的加热不敏感,从退相干的观点来看这点很重要.

The paper proposes a simple scheme to produce the GHZ state of N hot trapped ions. In this scheme, N two-levelions initially in the same state are confined in a linear trap and are simultaneously illuminated by two classi-cal homogeneous lasers. This scheme is insensitive to heating of vibratiunal motion, which is important in view of de-coherence.
