Figure 3

(a) Experimental simulation in a waveguide lattice implementing direct two-particle tunnelling and second-order pair tunnelling with a similar weight. (b) Numerical simulation including both contributions (EBH model). (c) Numerical simulation including only second-order pair tunnelling (BH model). (d) Fidelity (see main text for definition) of the experimental light distribution with that predicted by the EBH model (continuous line) and with that predicted by the standard BH model (dotted line).
