任意三粒子GHZ态和W态的概率隐形传态

Probabilistic Teleportation of Arbitrary Three-Particle GHZ and W State

  • 摘要: 构造了一个全新的由两个多粒子部分纠缠态组成的用于量子隐形传态(QT)的量子信道。利用构造的量子信道,提出了两个任意三粒子GHZ态和W态的受控概率隐形传态的三方方案。发送者执行贝尔态测量和单粒子测量,控制者执行贝尔态测量,接收者引入一个辅助粒子并执行相应酉操作,可实现任意三粒子GHZ态和W态的概率隐形传送。两个QT方案的总成功概率都是8d^2n^2 (其中dn是量子信道的系数)。

     

    Abstract: A new quantum channel composed of two multi-particle partially entangled states for quantum teleportation (QT) is constructed. Two explicit controlled probabilistic teleportation tripartite schemes are proposed for arbitrary three-particle partially entangled GHZ state and W state. The arbitrary GHZ state and W state can be teleported with a certain probability to the receiver who introduces an auxiliary particle and performs the corresponding unitary operation, with the help of the measurement of Bell-state and single-particle from the sender and the controller. The overall success probabilities of two QT schemes are both 8d^2n^2 (d and n are the coefficients of the quantum channel).
