The researchers varied classical optimizers, circuit types, repetition counts, simulators, basis sets and noise models. Calculations used quantum simulators.

The findings are simulation-based benchmarking, not an experiment on quantum hardware. The paper reports that basis-set and circuit choices affected energy estimates.
