论文摘要
提出了两个量子自旋霍尔绝缘子(QSHI)环之间的量子传送。在第一个QSHI环中生成量子状态,第二个QSHI环用作纠缠QSHI状态的量子通道。在外边的交点中,将联合检测器放置,从而允许钟状态分析。在钟状态测量之后,爱丽丝最初是由第一个QSHI环组成的QSHI环和第二个QSHI环中的一个旋转状态,允许Bob(由第二个QSHI环中的另一个旋转边缘状态组成),以实现对第二个QSHI环中第二个QSHI环中QSHI环中QSHI量子的相应控制,该控制量是QSHI环中的完整量子teportation qshi teportation qshi teportation qshi ridge ssshi ridge ridge rists the Qshi temportation the QSHI环中的相应控制。还表明,在爱丽丝经典交流之后使用的鲍勃(Bob)的桌子独立于第一个QSHI环中生成量子的方式。该描述表明,可以在二维(2D)拓扑边缘状态的上下文中充分实施量子传送,并在拓扑事项,无疏离系统以及与纺丝技术相关的量子技术的发展中,在量子信息方面打开视角。
A quantum teleportation between two quantum spin Hall insulator (QSHI) rings is proposed. A qubit state is generated in the first QSHI ring and the second is used as a quantum channel in entangled QSHI state. In the intersection of outer edges is placed a joint detector, allowing a Bell state analysis. After the Bell state measurement, Alice, that is composed originally of a qubit in the first QSHI ring and one spin state in the second QSHI ring, allows Bob, that is composed of the other spin edge state in the second QSHI ring, to realize the corresponding control of the tunneling amplitudes in the second QSHI ring, what implements a complete quantum teleportation between the QSHI rings. It is also showed that Bob's table, used after the classical communication by Alice, is the same independently the way the qubit is generated in the first QSHI ring. This description indicates that a quantum teleportation can be fully implemented in the context of two-dimensional (2D) topological edge states and opens perspectives in the scenario of quantum information in topological matter, decoherence free systems, as well as for the development of quantum technologies associated to spintronics and quantum computation.
