| 摘 要： | 提出了一个产生3个热囚禁离子GHZ态的简单方案.方案中处于相同初态的3个两级能离子被囚禁在一个线性阱中,同时被2个经典的均匀激光场驱动.本方案对离子的振动不敏感,从退相干的角度看这一性质非常重要.

| Abstract: | A simple scheme to produce the GHZ state of three hot trapped ions is proposed.In this scheme,three two-level ions initially in the same state are confined in linear trap and are simultaneously illuminated by two classical homogeneous lasers.This scheme is insensitive to heating of vibrational motion,which is important in view of decoherence. |
