In this paper, we propose a new scheme for faithful bidirectional quantum teleportation (BQT) of special type of two-qubit entangled states by using single G state as a quantum channel. In 2016, by using five-qubit and six-qubit entangled states as the quantum channels, two different BQT schemes were proposed by Sang ((2016) Int. J. Theor. Phys . 55 , 1333) and Hassanpour et al ((2016) Quantum Inf. Process. 15 , 905) respectively. In first scheme, Alice teleports a special type of two-qubit entangled state to Bob and at the same time Bob teleports a single qubit state to Alice. In later scheme, Alice and Bob teleport special type of two-qubit entangled state to each other simultaneously. In contrast to these schemes, in our proposed scheme Alice and Bob can teleport special type of two-qubit entangled states to each other simultaneously while the quantum channel is a four-qubit entangled state. Our proposed BQT scheme requires minimum consumption ...

以G态为量子通道的二量子纠缠态的双向量子隐形传态

在本文中,我们提出了一种新的方案,以单G状态作为量子通道,用于特殊类型的两量子位纠缠态的忠实双向量子隐形传态。在2016年,Sang((2016)Int。J. Theor。Phys。55,1333)和Hassanpour等人((2016 )(量子信息处理)15,905)。在第一种方案中,爱丽丝将特殊类型的两个量子位纠缠态传输到鲍勃,同时鲍勃将单个量子位纠缠态传输到爱丽丝。在以后的方案中,爱丽丝和鲍勃同时传送特殊类型的两个量子纠缠态。与这些方案相比,在我们提出的方案中,当量子通道为四比特纠缠态时,爱丽丝和鲍勃可以同时传送特殊类型的两个量子纠缠态。我们提出的BQT方案要求最低消耗量...
