摘要

我们用维格纳函数推导出量子态的二阶相关函数[公式：见文]的紧凑表达式，从而在[公式：见文]与相空间中的状态形状之间建立了直接联系。我们进行了一项实验，通过直接光计数同时测量[公式：见文]，并通过同差断层扫描重建Wigner函数。结果证实了我们的理论预测。这篇文章是主题“光的量子理论”的一部分。

Intensity correlations in the Wigner representation.

We derive a compact expression for the second-order correlation function [Formula: see text] of a quantum state in terms of its Wigner function, thereby establishing a direct link between [Formula: see text] and the state's shape in phase space. We conduct an experiment that simultaneously measures [Formula: see text] through direct photocounting and reconstructs the Wigner function via homodyne tomography. The results confirm our theoretical predictions.This article is part of the theme issue 'The quantum theory of light'.
