A quantum walker is a particle evolving coherently over a network of sites, and therefore has the ability to interfere with itself, contrary to its classical counterpart. The extension to many-particle quantum walks, together with non-vanishing particle-particle interactions, leads to many-particle interference phenomena which are controlled by the particles’ statistics (bosonic or fermionic), their degree of mutual distinguishability, and the interaction strength. We focus on the scenario of two interacting co-bosons (pairs of bound fermions) on a 1D lattice, systematically explore characteristic dynamical features as determined by the location in parameter space, and discriminate the observed behaviour against that of two elementary bosons.
