Nonexponential fidelity decay in randomized benchmarking with low-frequency noise
Nonexponential fidelity decay in randomized benchmarking with low-frequency noise
We show that nonexponential fidelity decays in randomized benchmarking experiments on quantum-dot qubits are consistent with numerical simulations that incorporate low-frequency noise and correspond to a control fidelity that varies slowly with time. By expanding standard randomized benchmarking analysis to this experimental regime, we find that such nonexponential decays are …
