Classically Augmented Zero-Noise Extrapolation
An arXiv preprint titled 'Classically Augmented Zero-Noise Extrapolation' introduces a method that incorporates classical computation into zero-noise extrapolation, a standard error mitigation technique for noisy quantum devices. The paper proposes using classical resources to improve the extrapolation process, potentially enhancing accuracy or reducing overhead.

If the method demonstrates consistent improvement across noise models, it could become integrated into open-source error mitigation libraries like Mitiq or Qiskit within two years.
These libraries already support ZNE, and a classically augmented variant that reduces bias or variance would be a straightforward drop-in replacement, provided it works across common noise models and requires minimal additional classical resources.
