摘要 用高灵敏度光谱仪实测纠缠点附近SPDC光场的波长-空间位置关系、强度-空间位置关系,辅助定位光场中的纠缠点位置,搭建双光子偏振纠缠源.测量不同条件下的符合对比度,计算Bell不等式,验证了量子力学的完备性.该方法提升了传统纠缠源实验的教学品质,同时降低此类传统实验的操作难度,减少学生完成纠缠源实验所需时. A quantum entanglement source was built by analyzing spontaneous parametric down-conversion （SPDC） light field though point location technique ,which employed a high sensitivity spectrograph as a pre-detector to measure the wavelength-space and intensity-space relations .Using this technique ,a high-quality bi-photon polarization entanglement source was obtained .The Bell ine-quality was calculated by measuring the coincidence contrast in different conditions ,and the complete-ness of quantum mechanics was verified .Consequently ,this made the traditional quantum entangle-ment experiment easier and efficient ,and it was possible to get more students involved in .
