From: Bright nanoscale source of deterministic entangled photon pairs violating Bell’s inequality
The sixteen cross-correlation measurements needed for the violation of the Clauser-Horne-Shimony-Holt inequality. The angles on the left specify how much the polarization detection angle α for the exciton (blue) and biexciton (red) is rotated with respect to the rectilinear basis in the laboratory reference frame. For each set of rotation the degree of correlation C b is extracted by measuring all four combinations between the biexciton (XX and \(\overline{{\rm{XX}}}\)) and exciton (X and \(\overline{{\rm{X}}}\)) photons. The insets show a magnification of the zero time delay peak.
