摘要:
提出一个以4粒子Cluster态和3粒子GHZ态作为量子信道实现单粒子未知态的分级量子通信方案.在本方案中,Alice发送一个量子态信息给6个接收者.首先,发送者对自己的2个粒子做Bell测量并将测量结果发送给所有的接收者; 其次,接收者分别对自己的粒子做单粒子测量; 最后,需要恢复秘密的接收者在部分或者所有接收者的帮助下,对接收到的测量结果做相应的幺正操作即可恢复未知态,完成本次量子通信.从外部攻击和内部攻击2个方面对方案的安全性进行了讨论,并证实其是安全可靠的.
Abstract:
A scheme is proposed for hierarchical quantum information splitting with a four-qubit cluster state and a three-qubit GHZ state.In this scheme, the sender Alice wants to distribute a quantum secret to six recipients.Firstly, Alice performs a joint measurement on her two qubits with Bell basis, and send the measurement results to all the recipients.Then, the recipients perform single-qubit measurement on their own qubit respectively.Finally, the corresponding recipient can reconstruct the unknown state by appropriate local operation.The security of the scheme is discussed from two aspects: external attack and internal attack, and it is proved to be safe and reliable.
