提出一个在腔QED中实现密集编码的方案.在这个方案中,发送者和接收者共享两个非最大二粒子纠缠态作为量子通道,通过对原子执行局域幺正变换,以一种简单的方法实现了最大纠缠态的密集编码.同时,完成了从非最大纠缠态到最大纠缠态的转换.

We propose a protocol for implementing probabilistic dense coding in cavity QED. The sender and the receiver share the non-maximally entangled quantum channel. We realize quantum dense coding in a simple way by performing unitary transformations on atoms. In the meanwhile, we complete conversion of entangled state from non-maximally entangled state to maximally entangled state.
