Engineering the electromagnetic environment of a quantum emitter gives rise to plethora exotic light-matter interactions. In particular, photonic lattices can seed long-lived atom-photon bound states inside band gaps. Here we report on concept and implementation novel microwave architecture consisting an array compact, high-impedance superconducting resonators forming 1 GHz-wide pass band, in which have embedded two frequency-tuneable artificial atoms. We study atom-field interaction access previously unexplored coupling regimes, both single- double-excitation subspace. addition, demonstrate coherent interactions between states, resonant dispersive that are suitable for SWAP CZ two-qubit gates. The presented holds promise simulation with tuneable-range photon transport experiments nonlinear regime.
