Rabi oscillations (purple circles) for a single hBN defect measured at high microwave power, fit to a function of the form exp(- t / T Rabi )sin(2 tOmega - phi ) (orange curve), where phi is the phase offset, Omega is the Rabi frequency and T Rabi is the decay lifetime of the Rabi oscillations. The inset shows a zoomed-in view of the data.
