Extended Data Fig. 5

a, Time dependence of the resonance frequencies f1 and f4 of Q1 and Q2, respectively. The exchange interaction is set to 2.5 MHz. The data have been offset by 6.9491 GHz and 6.9620 GHz for f1 and f4, respectively. b, Time dependence of the readout point obtained by sweeping along the detuning axis in a measurement identical to the one shown in Fig. 1d. The best readout point is achieved with a Gaussian fit of the visibility peak.
