| 摘要 | 为了解决任意二量子通信问题，首先给出了五粒子和七粒子纠缠态的构造方法，并提供了它们的量子线路图。其次，以该五粒子纠缠态为量子信道，提出一个任意二粒子未知量子态的受控隐形传态协议。该协议在监察者Charlie的控制下，Alice进行四粒子投影测量和经典通信，Bob采用简单酉变换就能以100%的概率成功重构一个任意二粒子纠缠态。最后，利用七粒子纠缠态为量子信道，提出了任意二粒子纠缠态的联合受控远程制备方案。在此方案中，发送者Alice用自己掌握被制备态的部分信息构造测量基，发送者Bob采用前馈测量策略，接收者Diana在监控者Charlie的帮助下，通过简单幺正变换就能确定性地恢复原始态。 |

| 英文摘要 | In order to solve the problem for arbitrary two-qubit quantum communication, this paper firstly gave the construction methods of five- and seven-particle entangled states, and provided their quantum circuit diagrams. Next, taking this entangled five-particle state as quantum channel, this paper proposed a controlled teleportation protocol for an arbitrary two-particle unknown quantum state. Under the control of the supervisor Charlie, Alice carried out four-particle projective measurement and classical communication, and Bob could successfully reconstruct an arbitrary two-particle entangled state with 100% probability by using simple unitary transformation. Finally, the paper put forward a joint controlled remote preparation scheme for an arbitrary two-particle entangled state by using the seven-particle entangled state as quantum channel. In this scheme, the sender Alice constructed a measurement basis with some information of the prepared state, which were had by her. The sender Bob used feed-forward measurement strategy, and the receiver Diana, with the help of the supervisor Charlie, could restore the original state deterministically by simple unitary transformation. |
