Extended Data Fig. 1: Cavity spectrum and parametric dispersive shifts of the L transmon.
From: Strong parametric dispersive shifts in a statically decoupled two-qubit cavity QED system
As with Fig. 2 in the main text for the R transmon, we performed the same measurements with the L transmon. (a) A typical cavity spectrum while sweeping the pump frequency ωp. The upper and lower panel shows the result with the L transmon in the ground state \(\left\vert {g}_{L}\right\rangle\) and the first excited state \(\left\vert {e}_{L}\right\rangle\), respectively. (b) The dispersive shifts as a function of the pump detuning frequency, ΔpL = ωp − (ωC − ωL), at various calibrated pump amplitudes, δϕp = 0.028 (red), 0.056 (orange), 0.084 (yellow), 0.112 (green), 0.14 (blue), and 0.168 (purple). The solid lines are the fits to the data from the theory. See the main text for more details.
