| 摘 要： | 本文提出一个用类W态作为纠缠通道,采用不同于文献19]的测量基来实现量子隐形传态的腔QED方案.在这个方案里,只需要利用原子和腔场通过J-C哈密顿量发生共振相互作用,一步就可制备纠缠通道.另外,通过原子与腔场的失谐作用,利用Bell态测量,可实现概率为100%的量子隐形传态.在目前的腔QED技术条件下,该方案是可以实现的. |

| Abstract: | An experimentally feasible protocol for realizing a perfect teleportation by using a class of W-state in cavity QED is proposed. In this scheme, we use Bell state as measurement bases which differ from the paper P. Agrawal,et al.,Phys.Rev.A 74(2006)062320], so we can exactly realize the perfect teleportation in experimentally. The distinct feature of this scheme lies on that the whole course is perfect, whatever from the generation of the entangled channel to the simpleness of the measurement bases. The scheme can be implemented by the present cavity QED techniques. |
