a Dependence of the IcRn product of device A2 on both the cold and hot branches as a function of temperature. b VI characteristic of device A2 at 650 mK. Voltage–current characteristic in the presence of a microwave radiation (c, d), histogram of the Josephson junction voltage as a function of the microwave power (e, f), and width of the Shapiro steps as a function of the microwave power (g, h) for samples A2 at 650 mK and a microwave drive of 4.2 and 11.5 GHz. The normalization follows the same conventions used in Fig. 2.
