摘要/Abstract

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远程地制备一个任意二量子态。该协议表明：仅当两个发送者与控制者相互合作，量子任务才能完全成功完成，且总的成功概率为100%。

Abstract: A scheme for hybrid bidirectional controlled quantum communication of arbitrary two-qubit states is proposed by using a nine-qubit entangled state as the quantum channel. In this scheme, two distant parties, Alice and Bob are not only senders but also receivers, and Alice can teleport an unknown arbitrary two-qubit state to Bob, at the same time, Bob can also help Alice remotely prepare an arbitrary two-qubit state. This protocol shows that only when two senders and controller collaborate with each other, the quantum task can be completed successfully, and the total success probability of this protocol is 100%.

Key words: hybrid bidirectional controlled quantum communication, teleportation, remote state preparation, arbitrary two-qubit state
