Hybrid physical/logical zero-noise extrapolation with limited logical executions

D. V. Babukhin, W. V. Pogosov

Mixing a few error-corrected points with many uncorrected ones reduces runtime for zero-noise extrapolation by orders of magnitude.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

For Richardson extrapolation, the mixed-data strategy reduces variance amplification and can lower the required physical runtime by several orders of magnitude when γ ≤ 0.1.

C2weakest assumption

The model assumption that error correction suppresses the effective gate error rate from p to a constant factor γp, independent of circuit depth or other parameters, which is used to derive the variance of the zero-noise estimator.

C3one line summary

Mixed physical-logical datasets for zero-noise extrapolation reduce estimator variance and physical runtime by orders of magnitude compared to pure logical or pure physical strategies when error correction suppresses noise by a factor of 0.1 or less.
