a−c Qubit transition spectrum as a function of the qubit frequency fq and the applied external magnetic flux Φ/Φ0 for device I (a), device II (b) and device III (c) extracted from Fig. 2f, g and h, respectively. The dashed black lines show fits to the qubit transitions obtained from the Hamiltonian in Eq. (2) using the single transparency model. d−f Normalized residual (fmodel − fmeas)/fmeas as a function of Φ/Φ0 for device I (d), device II (e) and device III (f), respectively.
