摘　　要：提出一个对未知三原子纠缠态辅助克隆的腔QED方案.该方案包括两个阶段,首先用两个两原子纠缠态和一个三原子纠缠态作为量子信道实现对未知三原子纠缠态的受控隐形传态,其次,在态制备者的帮助下,信息发送方实现对未知三原子纠缠态的辅助克隆.A scheme for controlled assisted cloning of an unknown three-atom entangled state is proposed. Firstly, controlled teleportation of an unknown three-atom entangled state can be realized by using two two-atom entangled states and a three-atom entangled state as the quantum channel. Secondly, Alice （the sender） can produce copies of an unknown three-atom entangled state with assistance of Victor （a state preparer）.
