摘要
分析了用级联的两个I类倍频腔产生的三色三组份纠缠光源纠缠特性,结果表明:第一个腔的反射抽运场,第二个腔的反射抽运场和第二个腔的输出倍频场之间是关联的,并给出了纠缠度随各种实验参数的变化关系,为多色纠缠光束的产生及其在量子测量与量子通信中的应用提供了参考。
Abstract
The entanglement properties of three-color and tripartite entangled state produced from two cascaded type I second-harmonic generation cavities are analysed. It is shown that the reflected pump beam of the first cavity, the reflected pump beam and the output second-harmonic beam of the second cavity are entangled, and the dependence of the entanglement degree on various experimental parameters is also analyzed. The scheme provides a reference for generation of multicolor entangled state and its application in quantum measurement and quantum communication.
