- Abstract: We report the analogue simulation of an ergodiclocalized junction by using an
array of 12 coupled superconducting qubits. To perform the simulation, we
fabricated a superconducting quantum processor that is divided into two
domains: a driven domain representing an ergodic system, while the second is
localized under the effect of disorder. Due to the overlap between localized
and delocalized states, for small disorder there is a proximity effect and
localization is destroyed. To experimentally investigate this, we prepare a
microwave excitation in the driven domain and explore how deep it can penetrate
the disordered region by probing its dynamics. Furthermore, we performed an
ensemble average over 50 realizations of disorder, which clearly shows the
proximity effect. Our work opens a new avenue to build quantum simulators of
driven-disordered systems with applications in condensed matter physics and
material science
