通过拉盖尔-高斯(LG)模的量子关联，观察到了光子的几何位相之一的古伊位相的影响。在实验中，两个不同LG模的测量基态的相对相位通过古伊相位被操纵，观察到的符合计数率与理论预测符合得很好。这一结果表明，Gouy相可以作为一种新的工具来操纵多维光子量子态。
The effect of the Gouy phase, which is one of the geometrical phases of photons, is observed through quantum correlation in Laguerre-Gaussian (LG) modes. In an experiment, the relative phase of two different LG modes of measurement basis states is manipulated via the Gouy phase, and the observed coincidence count rates agree well with theoretical predictions. This result suggests that the Gouy phase can be used as a new tool to manipulate multidimensional photonic quantum states.
