Collective effects on the light scattered by disordered media such as Anderson localization and coherent backscattering critically depend on the reciprocity between interfering optical paths. In this Letter, we explore the breaking of reciprocity for the light scattered by a disordered cold-atom setup, taking advantage of the noncommutation of optical elements that manipulate the polarization of the interfering paths.

Superconducting circuits are highly controllable platforms to manipulate quantum states, which make them particularly promising for quantum information processing. We show here how the existence of a distance-independent interaction between microwave resonators coupled capacitively through a qubit offers an alternative control parameter toward this goal.
