We aim to realize a 2D fluxonium coupled respectively to 4 and 12 on-chip lumped element resonators. We use a fast flux line to control the coupling between the Fluxonium qubit and the resonators. We have studied theoretically the emerging spin-Boson Hamiltonian for this particular circuit with the aim to measure revival effects in the coherent oscillations of the qubit. We started to implement measurements, revealing the effect of a small harmonic oscillator bath of 4 oscillators on the revival of the quantum coherence.
