Circuit infidelities for (a) single excitations, and (b) double excitations, for different number of qubits the gates act on, once with our decompositions (blue), and once with the one presented in ref. 24 (red). The statistics come from first sampling the frequency noise parameters paired with random excitation angles M = 5000 different times for each number of qubits. We then consider laser power fluctuations for each MS gate separately, thus resulting in averages over 10,000, and 20,000 experimental realizations of MS gates in our circuits for singles-, and doubles, respectively. Consequently, for the reference, we consider 20 000, and 80 000 realizations of MS gates. The markers show the mean of the respective distributions.
