Fig. 5: Experimental results for two-photon 2D-QW.

a In order to obtain a three-dimensional representation of the distributions, the two-dimensional lattice was linearized in the following way: (m, n) = m + 7n, with m, n ∈ [−3, 3]. The figure graphically shows the linearization map. b Comparison between the theoretical predictions and the measured experimental distributions with two-photon inputs. Shaded regions on top of each bar correspond to the experimental errors. The error bars were obtained through a bootstrapping approach. The bunching probabilities are highlighted by the yellow line.
