论文摘要
最近，Ri-Gui Zhou等。 [int。 J.理论。物理。 59，166-172（2020）]提出了一种通过利用六分数纠缠状态作为量子通道进行双向量子传送的方案。据观察，Zhou等人计算的固有效率。不正确。在这一改进的方案中，我们表明，可以使用优化的量子资源和更少的经典资源消耗来完成两二和两个量子量子状态的双向传送。我们还计算了改进方案的内在效率，这比周的方案要好得多。此外，我们还讨论了协议的安全性。
Recently, Ri-Gui Zhou et al. [Int. J. Theor. Phys. 59, 166-172 (2020)] proposed a scheme for bidirectional quantum teleportation of two-two and two-three qubit states by utilizing a six-qubit entangled state as a quantum channel. It is observed that the intrinsic efficiency calculated by Zhou et al. is not correct. In this improved scheme, we show that bidirectional teleportation of two-two and two-three qubit quantum states can be done by using optimized quantum resource and less consumption of classical resource. We also calculate the intrinsic efficiency of our improved scheme which is much better than the Zhou's scheme. Additionally, we also discuss about the security of the protocol.
