  Multiple bosons undergoing coherent evolution in a coupled network of sites
constitute a so-called quantum walk system. The simplest example of such a
two-particle interference is the celebrated Hong-Ou-Mandel interference. When
scaling to larger boson numbers, simulating the exact distribution of bosons
has been shown, under reasonable assumptions, to be exponentially hard. We
analyze the feasibility and expected performance of a globally connected
superconducting resonator based quantum walk system, using the known
characteristics of state-of-the-art components. We simulate the sensitivity of
such a system to decay processes and to perturbations and compare with coherent
input states.
