Rabi oscillations between phonon modes c (b) and the qubit in the top (bottom) plot for 82 values of the resonant interaction duration . The circles are the data and the black lines are fits. The extracted Fock-state populations for each mode is shown in the histograms on the right side. The vertical error bars on the histograms (grey) account for one standard deviation of the fit uncertainty and are below 1%.
