摘要 以Bell不等式的推广形式CHSH不等式为理论指导,利用自主搭建的双光子纠缠源制备光子纠缠态,通过测量不同条件下符合对比度计算Bell不等式,验证了量子力学的完备性. Entanglement is prepared based on the CHSH inequality,the extended form of Bell inequality and a self-made system of two-photon entanglement source.The Bell inequality is calculated by measuring the coincidence contrast in different conditions.Thus the completeness of quantum mechanics is verified.
