实验证明了双光子对称性对多重散射无序系统中空间量子关联传播的重要性。两个可区分的纠缠光子具有可调的空间交换对称性发送通过散射介质。两个光子被观察到有一个整体平均的趋势，聚集在一起（玻色子对称性）或避免彼此（费米对称性）。一个中间程度的集群观察任意交换对称性。
We experimentally demonstrate the importance of two-photon symmetry for the propagation of spatial quantum correlations in a multiple-scattering disordered system. Two distinguishable entangled photons with tunable spatial exchange symmetry are sent through the scattering medium. The two photons are observed to have an ensemble-averaged tendency to cluster together (bosonic symmetry) or to avoid each other (fermionic symmetry). An intermediate degree of clustering is observed for anyonic exchange symmetry.
