Rigorous, cross-benchmarking verification protocol on 51-ion quantum processor assigns formal error bounds to analog simulations

"quantum simulators model complex many-body physical systems that exceed classical computing limits, but uncorrected hardware drift, environmental noise, measurement uncertainties make predictions difficult to verify... overcome extracting physical dynamics from experimental data (based on Hamiltonian/ Lindbladian learning rather than idealized theoretical models), propagating learned statistical uncertainties into calculated physical observables... analog quantum simulators for trusted scientific predictions"
