Noise-Aware Quantum Amplitude Estimation by Steven Herbert, Ifan Williams, Roland Guichard, Darren Ng

“…We provide results from quantum amplitude estimation run on various IBM superconducting quantum computers and on Quantinuum's H1 trapped-ion quantum computer to show that the proposed model is a good fit for real-world experimental data. …”

Dynamical quantum maps for single-qubit gates under universal non-Markovian noise by J. M. Sánchez Velázquez, A. Steiner, R. Freund, M. Guevara-Bertsch, Ch. D. Marciniak, T. Monz, A. Bermudez

“…We gauge our predictions for experimentally relevant metrics against established characterization techniques run on a trapped-ion quantum computer. In particular, we find that experimental estimates of average gate errors measured through randomized benchmarking and reconstructed via quantum process tomography are tightly lower-bounded by our analytical estimates, while the depolarizing model overestimates the gate error. …”
