任意量子态远程传输的实验研究

A continuous variable entanglement quantum teleportation was realized experimentally with a single type II phase matching Optical Parametric Oscillator (OPO). Phase correlation and amplitude anti-correlation entanglement can be generated in the process of parametric deamplification directly with type II phase matching OPO, and then a self-homedynie balance detector system can be used in the measurement. It will simplify the quantum communication and also be used in practice conveniently.

我们拟通过II类相位匹配非线性晶体连续光学参量振荡器，运转于阀值以下，产生双模压缩纠缠态，利用此纠缠态的非定域性，进行量子态远程传送的实验研究。把真空态或相干态作为输入态，对输入场与纠缠态的一半进行联合测量，同时测量实部与虚部。将此作为经典信息，用于将纠缠态的另一半变换为输入态，完成态的传输。..
