If the stability conditions are explicit and computable, this could allow experimental groups to select quantum error-correcting codes whose thresholds remain robust under small mismatches in noise modelling during the next two years.
Near-term devices have imperfect noise characterization, and codes with perturbatively stable thresholds would reduce the risk that threshold estimates degrade under realistic deviations from ideal noise assumptions.
