(a,b) X0, X1− resonance fluorescence versus detuning δ at 4.2 K, B=0.0 mT with 100 ms integration time per point. The solid lines are Lorentzian fits to the data. The linewidths are 
, 
; the Rabi energies Ω/Γ0=0.5 (X0), 0.4 (X1−); and transform limits 
, 
. (c) RF linewidth against scanning frequency dδ/dt/Γ0. Γ approaches Γ0 for scanning frequencies above 50 kHz. For each scanning frequency, the error bar represents the s.d. of several hundred linewidth scans. Solid lines represent a Lorentzian fit of the data with linewidth 30±3 kHz.
