We demonstrate experimentally the frequency-time entanglement of photon pairs produced in a CW-pumped quasi-phased-matched AlGaAs superlattice waveguide. A visibility of 96.0±0.7% without background subtraction has been achieved, which corresponds to the violation of the Bell inequality by 52 standard deviations.
我们通过实验证明了在连续波泵浦的准相位匹配AlGaAs超晶格波导中产生的光子对的频率-时间纠缠。在不进行背景扣除的情况下,实现了96.0±0.7%的可见度,这相当于贝尔不等式被违反了52个标准差。
