Abstract

We present analytic expressions for the coincidence detection probability amplitudes of photon pairs generated by spontaneous parametric down-conversion in both momentum and position spaces, without using the Gaussian approximation and taking into account the effects of birefringence in the nonlinear crystal. We also present experimental data supporting our theoretical predictions, using Einstein-Podolsky-Rosen correlations as benchmarks, for eight different pump beam configurations.

自发参量下变频中的爱因斯坦-波多尔斯基-罗森相关性：超越高斯近似

我们提出了自发参数下变频产生的光子对在动量空间和位置空间的重合探测概率振幅的解析表达式，不使用高斯近似，并考虑了非线性晶体中双折射的影响。我们还以爱因斯坦-波多尔斯基-罗森相关性为基准，针对八种不同的泵浦光束配置，给出了支持我们理论预测的实验数据。
