我们首先扩展我们最近的实验空间量子相关成像通过薄散射介质的情况下，两个相位散射板分别放置在图像和傅立叶平面的双光子源，模仿厚散射介质。双光子之间的空间相关性仍然在量子水平上被检测到，但不再以双光子斑点状图案的形式存在。然而，我们发现，非常高维的空间纠缠可以通过厚的散射介质中恢复适度的损失，在空间和时间域中没有任何公平的采样假设。第二，数值模拟的双光子波函数的开发和应用到我们的实验情况下，有很好的协议。
We first extend our recent experiments of spatial quantum correlations imaging through thin scattering media to the case where two phase scattering plates placed respectively in the image and the Fourier planes of the biphoton source, mimics a thick scattering medium. Spatial correlations between twin photons are still detected at the quantum level but no more in the form of two-photon speckle-like patterns. However, we show that spatial entanglement of very-high dimensionality can be retrieved through thick scattering media with moderate losses and without any fair sampling assumption in the space and time domains. Second, a numerical simulation of the biphoton wave function is developed and applied to our experimental situation, with a good agreement.
