Abstract
Two simultaneous quantum teleportation schemes are proposed by utilizing the four-qubit cluster state as quantum channels. In each scheme, there are three legitimate participants, that is one sender Alice and two receivers Bob and Chris. Taking advantage of the pre-shared quantum entanglement resources and some necessary local quantum operations as well as classical communication, Alice can concurrently transmit two independent unknown target quantum states to Bob and Chris, respectively. In the first scheme, the target states are two arbitrary single-qubit states, while in the second scheme they are two unknown multi-qubit entangled states. The proposed schemes are simply to implement because of requiring only single-qubit measurements and Pauli operations as well as two-qubit unitary operations.
利用四量子比特簇状态作为量子信道,提出了两种同步量子远距传输方案。每个方案都有三个合法参与者,即一个发送者 Alice 和两个接收者 Bob 和 Chris。利用预先共享的量子纠缠资源和一些必要的局部量子操作以及经典通信,爱丽丝可以同时将两个独立的未知目标量子态分别传送给鲍勃和克里斯。在第一种方案中,目标态是两个任意的单量子比特态,而在第二种方案中,目标态是两个未知的多量子比特纠缠态。由于只需要单量子比特测量和保利运算以及双量子比特单元运算,拟议方案的实现非常简单。
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.
