a Tunnelling conductance as a function of perpendicular magnetic field B⊥ for microwave (MW) irradiation with frequency f = 9.20 GHz and power P = − 5 dBm. Green dashed lines mark bound state replicas with effective transmission \(\bar{\tau }=0.84\). b, c Same as a for P = 0 dBm and P = 5 dBm, respectively. d Current–phase relation as a function of MW power (circles) fitted with an adiabatic theory (lines), for MW frequency f = 9.20 GHz. Traces are successively offset by 2.05 μA. Deviations of the data from the adiabatic theory at high power are marked with arrows. e Microwave field strength α obtained from the adiabatic theory fit presented in d, with error bars showing the uncertainty in the fit parameter to one standard deviation. Data was taken at VTG = − 0.8 V and VT = − 2.11 V.
