摘要：

We present a simple scheme for implementing controlled dense coding by using a five-atom cluster state. In cavity QED systems, we have proposed to generate a five-atom cluster state and demonstrated that the four-atom entangled states can be exactly distinguished. Thus our approach can be realized with present cavity QED techniques.
