用于连续变量隐形传态的量子开关

Quantum Switch for Continuous Variable Teleportation

Junxiang Zhang, Changde Xie, Kunchi Peng

摘要:

提出了一种用于连续变量隐形传态的新型量子开关。将两对具有相同频率和恒定相位关系的EPR光束在两个分束器上合成,产生两对条件纠缠光束,其中两对被发送到两个发送站(Alices),另一对被发送到两个接收站(bobs)。EPR纠缠最初是由双模正交压缩态光场产生的。将其中一个EPR源的压缩分量在振幅和相位之间进行转换,发送端的输入量子态将依次在两个接收端再现。利用压缩态光操纵的开关系统有望成为一种实用的量子开关器件,用于量子信息的通信和隐形传态。

英文摘要:

A novel quantum switch for continuous variables teleportation is proposed. Two pairs of EPR beams with identical frequency and constant phase relation are composed on two beamsplitters to produce two pairs of conditional entangled beams, two of which are sent to two sending stations(Alices) and others to two receiving stations(bobs). The EPR entanglement initionally results from two-mode quadrature squeezed state light. Converting the squeezed component of one of EPR sources between amplitude and phase, the input quantum state at a sender will be reproduced at two receivers in turn. The switching system manipulated by squeezed state light might be developed as a practical quantum switch device for the communication and teleportation of quantum information.
