Abstract
An asymmetric bidirectional quantum teleportation scheme was proposed by utilizing a seven-qubit entangled state as quantum channel. The scheme can perfectly achieve the transmission of a three-qubit target entangled state from one legitimate user Alexis to the other legitimate user Billy. Simultaneously, another two-qubit target entangled state can be reversibly conveyed from Billy to Alexis. The implementation of the scheme requires only Bell-state measurements and some simple necessary quantum operations. The impact of phase-damping noise on our scheme is investigated by calculating and discussing its fidelity. Compared with some analogous schemes, the proposed scheme has many significant advantages, such as less quantum and classical resources consumed, higher intrinsic efficiency, lower execution difficulty. Furthermore, it has strong compatibility and experimental feasibility.
利用七量子比特纠缠态作为量子信道，提出了一种非对称双向量子远传方案。该方案可以完美地实现从一个合法用户 Alexis 向另一个合法用户 Billy 传输一个三量子比特的目标纠缠态。与此同时，另一个两量子比特的目标纠缠态也能从比利可逆地传输给亚历克西斯。该方案的实现只需要钟态测量和一些简单必要的量子操作。通过计算和讨论其保真度，研究了相位阻尼噪声对我们方案的影响。与一些类似方案相比，所提出的方案具有许多显著优势，如消耗的量子和经典资源更少、内在效率更高、执行难度更低。此外，它还具有很强的兼容性和实验可行性。
