From: Fast camera spatial characterization of photonic polarization entanglement
Table of S-values for sub-area matrices. In this configuration, the two areas on the fast camera that are illuminated by photons from the fibers are divided into subareas, forming two 3 × 3 matrices. The coincidence thus decomposes into that of 81 possible pairs of a combination of subareas. Using these coincidences, we calculated the CHSH inequality violation and plotted the resulting S-values in the form of 81 blocks in nine 3 × 3 matrices. The S-values are color-coded with the corresponding uncertainty shown in the center of the box. This produces an intuitive illustration of the spatial distribution of entangled photon pairs. The digits above each matrix give the position of the photon in the first fiber: 0 × 0 corresponds to the top left corner, 0 × 2 to the top right corner, 1 × 1 to the center.
