a Rabi oscillations as a function of the qubit drive power P and the Rabi pulse duration τRabi at 0.5 Φ0. b Rabi frequency fRabi extracted from (a) as a function of 10P(dB)/20, which is proportional to the qubit drive amplitude \(\sqrt{P}\). c Energy relaxation time T1 measured at Φ = 0.5 Φ0. The solid red curve is an exponential fit with time constant T1 ~ 230 ns. d Ramsey coherence time \({T}_{2}^{*} \sim 39\,{{{\rm{ns}}}}\) measured at Φ = 0.5 Φ0.
