Extended Data Fig. 4: PESOS and Rabi oscillations at the high-fidelity point.

a, PESOS map acquired with microwave drive applied to the CB1 gate. b, A PESOS map acquired using the same configuration as for Fig. 4, with microwave drive applied to the J-gate. Both a and b use the same source power of 20 dBm, however variation in line losses due to different electronics may result in differences in electric field amplitude applied to the CB1- and J-gates. c, Rabi oscillations in the same configuration as Fig. 4a,b with an oscillation frequency of fRabi = 4.6 MHz, and a quality factor of 58.
