In 2017, Chen et al. [Quantum Inf. Process. 16 (2017) 201] proposed a scheme for cyclic quantum teleportation (CYQT) of three single-qubit information states among three participants by using six-qubit entangled state as a quantum channel. Following the work of Chen et al., we propose a new scheme for CYQT in which four participants cyclically teleport four arbitrary single-qubit information states among themselves by using two G-states as a quantum channel. In our scheme, reverse CYQT can also be realized throughout changing the qubit pairs to be measured by each participant. We also generalize our scheme for CYQT of N-qubit entangled states.

通过 G 态进行循环量子隐形传态

2017年，陈等。[量子信息。过程。 16(2017) 201] 通过使用六量子比特纠缠态作为量子通道，提出了三个参与者之间的三个单量子比特信息状态的循环量子隐形传态 (CYQT) 方案。跟随陈的工作等人.，我们提出了一种新的CYQT方案，其中四个参与者通过使用两个循环传送四个任意单量子比特信息状态。G-状态为量子通道。在我们的方案中，也可以通过更改每个参与者要测量的量子比特对来实现反向 CYQT。我们还推广了我们的 CYQT 方案ñ-量子位纠缠态。
