摘要

提出一个量子隐形传态的新方案. 通过对一对压缩参数相同但相互独立的双模压缩真空态(1-2和3-4量子态系统)中的2-3系统施行粒子数-相位的联合测量,制备出另外两体系统(1-4系统)的纠缠态作为纠缠源,从而实现量子隐形传态.

A new quantum teleportation protocol is addressed in this article. By performing the joint measurement of number-phase on a pair of independent two-mode squeezed vacuum states (1- 2 and 3- 4 systems), whose squeezed parameters are the same, the entangled states of the other two bodies (1- 4 systems) as the entangled resource are prepared. Thus the quantum teleportation is successfully realized.
