In this experiment, we couple a superconducting Transmon qubit to ahigh-impedance $645\ \Omega$ microwave resonator. Doing so leads to a largequbit-resonator coupling rate $g$, measured through a large vacuum Rabisplitting of $2g\simeq 910$ MHz. The coupling is a significant fraction of thequbit and resonator oscillation frequencies $\omega$, placing our system closeto the ultra-strong coupling regime ($\bar{g}=g/\omega=0.071$ on resonance).Combining this setup with a vacuum-gap Transmon architecture shows thepotential of reaching deep into the ultra-strong coupling $\bar{g} \sim 0.45$with Transmon qubits.
