摘 要:
提出一种方案用于隐形传送未知原子态，方案基于两个耦合双能级原子与一个单模腔场的非共振相互作用。方案要求腔场处于相干态，这使得方案容易实现。原子与相干腔场相互作用以后，腔场仍然处于相干态，通过探测原子的状态，即可将一个未知原子态隐形传送。方案也可以用于隐形传送未知原子纠缠态。[著者文摘]

Teleportation of an unknown atomic state in cavity QED

Abstract:
A scheme is proposed for teleportation of an unknown atomic state based on the nonresonant interaction of two coupled two-level atoms with a single-mode cavity field. The scheme only requires the cavity field to be in a coherent state. After the interaction between the atoms and the cavity, the cavity is left in a coherent state. By detecting the states of atoms, an unknown atomic state is teleported. The scheme can also be used to teleport an unknown atomic entangled state.[著者文摘]
