Extended Data Fig. 6

a, Raman transitions between qubits 1 (red) and 2 (blue), immediately after tuning both sidebands individually to 5 MHz. The simulation (solid lines) matches the data (circles) with a 0.36 MHz detuning term on the bus (Eq. (6)). b,c, Simulation of the excited state population for qubits 1 (red) and 2 (blue) as a function of the drive detuning and time, assuming tuned up sidebands and no bus detuning. d,e, Data for the detuned swaps for the left and right qubit. In the simulation plots, ‘X’ marks a point of interest: in ref. 22 this point corresponds to an entangling gate. Here, we only predict a concurrence of 0.91 at this point, lower than what can be achieved using the stroboscopic approach shown in Fig. 3e of the main text.
