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 two-particle quantum walks leads to the introduction of interactions and many-particle interference depending on the particles' statistics (bosonic or fermionic) and their distinguishability. We compare the quantum walk of two interacting cobosons (two pairs of bounded fermions) on a 1D lattice with that of two elementary bosons, and investigate to which extent the composite nature of the cobosons affects their dynamics.
