基于五粒子团簇态实现经济和简单的二粒子任意态的可控隐形传态
Economic and Simple Controlled Teleportation of an Arbitrary Twoqubit State Using Fivequbit Cluster State
摘要
通过对五粒子团簇态新应用的研究,提出了一个经济和简单的二粒子任意态的可控隐形传态方案.在这个方案中,发送者(Alice)、控制者(Charlie)和接收者(Bob)共享一个五粒子团簇态,发送者只需要执行Bell基测量,而控制者也仅需要执行单粒子投影测量.接受者根据发送者和控制者的测量结果,对自己拥有的粒子做适当的幺正变换,就可以重建发送者的二粒子任意态.这个可控隐形传态方案是决定性的,成功的概率为100%.与使用相同的量子信道进行二粒子任意态的可控隐形传送方案相比,不需要执行多粒子的联合测量,从而使得这个方案更加简单.
Abstract
A new application of the fivequbit cluster state is investigated for economic and simple controlled teleportation of an arbitrary twoqubit state. In this scheme, a fivequbit cluster state is shared by a sender (Alice), a controller (Charlie) and a receiver (Bob), and the sender only needs to perform Bellstate measurements and the controller performs a singlequbit projective measurement. The receiver can reconstruct the arbitrary twoqubit state by performing some appropriate unitary transformations on his qubits after he knows the measured results of both the sender and the controller. This controlled teleportation scheme is deterministic, and the probability of successful controlled teleportation is 100%. In comparison with the controlled teleportation scheme using the same quantum channel, the proposed scheme do not need to make multiparticle joint measurement that makes this scheme simpler.
