Figure 3a shows Rabi oscillations taken while varying the detuning δ . With increasing ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi j jδ , the frequency of the Rabi oscillations Ω 0 ¼
Fig. 5 Schematic of our microwave-generation apparatus. Two channels of an AWG produce square waves with an amplitude ratio of tan ϕ μw
Fig. 6 A typical experimental cycle. The nuclear-spin bath is prepared using a Raman cooling technique for 4 μ s, before electron spin control is performed
