| 摘 要： | 在腔QED系统中,我们用一个两原子的Bell态作为量子信道,提出了一个简单的任意单原子的隐形传态方案。在该方案中,通过引入一个辅助原子,可以用单原子的测量来代替Bell基测量,并且成功传送的概率能够达到1。此外,方案不受腔损和热场的影响。

| Abstract: | We present a simple scheme for teleporting an unknown atomic state using an atomic Bell state in cavity QED system.Our scheme can use single-atom detection instead of Bell-state measurement with the help of an auxiliary atom,and its successful probability can reach 1.In addition,the scheme is insensitive to the cavity decay and the thermal field. |
