We report the successful design and experimental implementation of three coincident nonlinear interactions, namely ZZZ (type 0), ZYY (type I), and YYZ/YZY (type II) second-harmonic generation of 780 nm light from a 1560 nm pump beam in a single, multigrating, periodically poled KTiOPO(4) crystal. The resulting nonlinear medium is the key component for making a scalable quantum computer over the optical frequency comb of a single optical parametric oscillator.
我们成功设计并实验实现了三种重合的非线性相互作用，即 ZZZ（类型 0）、ZYY（类型 I）和 YYZ/YZY（类型 II），将 1560nm 泵浦光束的 780nm 光转换为二次谐波，这是在单个多光栅、周期极化的 KTiOPO(4)晶体中实现的。这种非线性介质是在单个光参量振荡器的光频梳上构建可扩展量子计算机的关键组件。
