参量下转换（PDC）是一种在产生非经典光子数关联孪生光束中具有普遍实验意义的技术。PDC作为双模压缩过程的标准理论预测和零差测量观察到每个光束的热光子数分布。最近的实验得到了相互矛盾的分布。在这篇文章中，我们解释了一个先验的理论模型，完全基于直接访问的物理量的观察。我们比较我们的预测与实验数据，发现很好的协议。
Parametric down-conversion (PDC) is a technique of ubiquitous experimental significance in the production of nonclassical, photon-number-correlated twin beams. Standard theory of PDC as a two-mode squeezing process predicts and homodyne measurements observe a thermal photon number distribution per beam. Recent experiments have obtained conflicting distributions. In this article, we explain the observation by an a priori theoretical model solely based on directly accessible physical quantities. We compare our predictions with experimental data and find excellent agreement.
