Extended Data Fig. 7

a, Rabi oscillation for a third qubit measured on a different device than qubits 1 and 2. The qubit was measured at an external magnetic field of B = 0.675 T, giving a Larmor frequency of 18.757 GHz. From fitting the curve, we extract a Rabi frequency of 1.4 MHz. b, Spin-up probability versus burst duration and microwave frequency in a slightly different tuning regime. The expected Chevron pattern is visible. We observed a second (spurious) quantum dot in the vicinity of qubit 3 and expect that hybridisation with this extra quantum dot is limiting the \(T_2^\ast\) and also the \(T_{2,Rabi}\) of qubit 3.
