Cavity-driven Rabi oscillations. a Measurement of the atoms in state |2, 0〉 reveals resonant Rabi oscillations between |1, −1〉 and |2, 0〉 for a cavity-driving frequency of ω 0 = 2π · 6.83242 GHz. The chip temperature was set to T = 6.9 K. The red solid line is a fit to the damped oscillation, and the black line shows the result of the numerical simulations. b Timing sequence and c level scheme for the driven one-photon Rabi oscillations. d Temperature dependence of the cavity resonance frequency. The circles and error bars indicate the peak and the width (±κ) of the cavity line obtained from fits to the resonator transmission data. The solid and dashed lines indicate the fitted temperature dependence of the cavity frequency and linewidth (Supplementary Note 3 for details). The horizontal dotted line indicates the driving frequency, corresponding to the atomic resonance. e Temperature dependence of the Rabi frequency. While the cavity is driven at the same frequency ω 0 for all measurements, the temperature dependence of the cavity resonance leads to a change in the microwave intensity. Error bars indicate the confidence interval of the Rabi frequency measurement
