Controlling light-matter based quantum systems in the strong coupling regime allows for exploring quantum simulation of many-body physics in nowadays architectures. The atom-field interaction in a cavity QED network provides control and scalability for quantum information processing. Here, we propose the control of single- and two-body Jaynes-Cummings systems in a non-equilibrium scenario, which allows us to establish conditions for the coherent interchange of polariton species. Furthermore, the incoherent interchange triggered by cavity and atomic losses, exhibits a detuning-dependent asymmetry in the absorption spectrum. Finally, our findings are featured in the framework of the Superfluid-Mott Insulator quantum phase transition.
