四原子一般W态的确定隐形传态方案

Scheme for deterministic quantum teleportation of four-atom entanglement general W state

提出一个基于QED腔技术的四原子一般W态的确定隐形传态方案.方案将联合贝尔态测量转化为两个单原子态的测量,从而实现四原子一般W态的确定隐形传态,该方案成功的概率可以达到1,并且不受腔衰减和热场的影响.

A deterministic teleportation scheme for four -atom entanglement general W state was proposed in cavity QED. In our scheme, the Bell state measurement could be exactly converted into two separate atomic measurements on the two involved atoms, thus by only single - qubit measurements one can fulfill the scheme. The success probability could reach 1.0. In addition, the scheme was insensitive to both the cavity decay and the thermal field.
