PDC：参数化下转换
参数化下转换（Parametric Down Conversion，简称PDC）是一种常见的光学非线性过程，广泛应用于量子光学、量子信息处理及光子技术等多个综合研究领域。该术语常缩写为PDC，便于书写和学术交流。其核心原理是通过非线性晶体将单个高能光子转换为两个低能光子，是实现纠缠光子对和单光子源的重要技术手段之一。
Parametric Down Conversion具体释义

例句
- We use the parametric down conversion to generate pseudo two-fold copy of four-dimensional two-photon state and measure its I-concurrence by detecting the photon bunching effect.
- 因为直接利用了光子不可区分性引起的光子聚束现象，在实验室无需一一检测光子态；
- For the phase matching problem in spontaneous parametric down conversion, two models were put forward and analyzed.
- 对于自发参量下转换方法制备的纠缠光源，针对相位匹配提出并分析了两种数学模型。
- Theoretical calculation and analysis based on non-collinear phase matching condition show that it comes from the type-I spontaneous parametric down conversion and its second harmonic generation, having the opposite sequence to the colored conical emission rings.
- 基于非共线位相匹配理论计算和分析表明，这是一个由Ⅰ类自发参量下转换和其倍频过程的级联二阶参量过程，和彩虹圆锥角辐射的级联顺序正好相反。
