Fig. 4. Quantum state control of a rapidly rotating qubit.

Fig. 4

(A) Varying the duration of the microwave pulse in the sequence depicted in Fig. 3A results in time-domain Rabi oscillations, which we detect by computing the normalized fluorescence. a.u., arbitrary units. (B) We demonstrate quantum state control of the NV spin throughout the rotation by first applying a π pulse at t = 0 and then applying a variable duration microwave pulse at t = Trot/2 at which the NV has moved 20 μm away from its initial position. We then observe Rabi oscillations with the NV initialized to the mS = −1 state. Error bars are SE in computed fluorescence ratios from >105 experimental repetitions.
