Optimization of the CNOT gate fidelity. a Convergence of different optimization runs to the optimal gate fidelity. The solid black line and the shaded area represents the average and the standard deviation values over 512 runs. Seven example runs are shown in the background (dotted lines). b Gate fidelity versus the maximum allowed interaction level Γmax, at a constant Jmax = 4π. c Gate fidelity for different maximal tunneling rates Jmax at a constant maximal interaction level of Γmax = 20π
