(color online) (a) Measured S₂₁ spectrum at different probe amplitude and frequency. The DC bias of the Xmon is set to 0 and there is no microwave field applied to the λ/4 coplanar waveguide resonator. A peak appears at while reducing the probe power. (b) S₂₁ data of taken at a probe microwave at power of −134 dBm.
