From: Fast camera spatial characterization of photonic polarization entanglement
Distribution of time difference between two photons in different fibers for selected pairs of polarization settings combinations: α = 0° (blue), α = 40° (orange), α = 80° (red) and α = 120° (green) with β = 90°. The amplitudes for different polarization combinations are determined by the entangled state projection. Flat background results from uncorrelated photon background. The total number of coincidences is calculated by integration over the Gaussian curves.
