摘要

利用八量子比特簇态作为量子信道，最近提出了一种非对称双向受控量子远传方案[Int. J. Theor. Phys. 61, 17 (2022)]。在该方案中，有两个代理 Alice 和 Bob，以及一个控制器 Chris。在查理的监督和协助下，爱丽丝可以将一个未知的二量子纠缠态传送给鲍勃，同时，鲍勃也可以将一个未知的三量子纯态传送给爱丽丝。然而，该方案需要进行三量子比特 GHZ 状态测量和四量子比特 GHZ 状态测量。在本文中，我们对其进行了优化，使其只需进行单量子比特测量即可完成相同的量子任务。

Optimizing Asymmetric Bidirectional Controlled Quantum Teleportation Via Eight-Qubit Cluster State

Utilizing eight-qubit cluster state as quantum channel, an asymmetric bidirectional controlled quantum teleportation scheme [Int. J. Theor. Phys. 61, 17 (2022)] is proposed recently. In the scheme, there are two agents Alice and Bob, and a controller Chris. Under the supervision and assistance of Charlie, Alice can teleport an unknown two-qubit entangled state to Bob, and at the same time, Bob can also teleport an unknown three-qubit pure state to Alice. However, a three-qubit GHZ-state measurement and a four-qubit GHZ-state measurement are required in the scheme. In this paper, we have optimized it so that only single-qubit measurements need to be performed to complete the same quantum task.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
