The paper proposes a novel protocol of asymmetric cyclic controlled quantum teleportation, using a maximally nine-qubit entangled state as the quantum channel. In this protocol, communicants can simultaneously transmit two arbitrary two-qubit entangled states and an arbitrary single-qubit state. That is to say, Alice can transmit an arbitrary two-qubit state to Bob, Bob can transmit an arbitrary two-qubit state to Charlie, and Charlie can send an arbitrary single-qubit state to Alice via the control of David. Finally, the paper also analyzes and discusses the fidelity of the protocol in five different noise environments.

该论文提出了一种新的非对称循环控制量子隐形传态协议，使用最多 9 个量子比特的纠缠态作为量子通道。在这个协议中，通信者可以同时传输两个任意的双量子位纠缠态和一个任意的单量子位态。也就是说，Alice 可以向 Bob 传输任意的 2 量子比特状态，Bob 可以向 Charlie 传输任意的 2 量子比特状态，而 Charlie 可以通过 David 的控制向 Alice 发送任意的单量子比特状态。最后，本文还对协议在五种不同噪声环境下的保真度进行了分析和讨论。
