基于腔QED实现确定的多方受控的隐形传送任意两原子态方案

Scheme for Deterministic and Multi-controlled Teleportation of an Arbitrary Two-atom State in Cavity QED

基于腔QED系统提出一种实现确定的多方受控的隐形传送未知的任意两原子态的简单方案.该方案利用多原子与腔的共振相互作用分别一步实现作为量子信道的特殊纠缠W态的制备和所需的幺正变换,而且完成隐形传态所需时间不随接收方的增多而增长.

A simple scheme for deterministic and multi-controlled teleportation of an arbitrary unknown state for two-level atoms with a cavity QED system is proposed. In the scheme, the special entangled W states used as quantum channels and the requisite unitary transformations may be achieved via a single resonant interaction of the atoms with a cavity mode, respectively. The required time to complete the whole procedure does not increase with the number of agents.
