摘　　要：以九量子纠缠态为量子信道,提出了任意二量子态的混合双向受控量子通信协议.在该协议中,位于遥远两方的Alice和Bob既是发送者又是接收者,Alice能够传送一个未知任意二量子态给Bob,同时Bob也能够帮助Alice远程制备一个任意二量子态.该协议表明:仅当发送者与控制者相互合作,量子任务才能成功完成,且总的成功概率为100%.A hybrid bidirectional con trolled quantum communication protocol for arbitrary two-qubit st ates is proposed by using a nine-qubit entangled state as quantum channel.In this protocol,two distant parties,Alice and Bob,are not only senders but also receivers.Alice can teleport an unknown arbitrary two-qubit state to Bob,and at the same time,Bob can also help Alice prepare an arbitrary two-qubit state remotely.This protocol shows that only when the sender and the controller collaborate with each other,the quantum task can be completed successfully,and the total success probability of this protocol is 100%.
