Recent progress and challenges in error mitigation with fixed-frequency superconducting quantum processors

Abstract

Superconducting quantum processors have recently made tremendous improvements in both quality and scale. Concurrent progress in error mitigation techniques has now enabled the application of these to quantum circuits at scales beyond exact classical simulation. In this talk, I will first discuss experimental challenges for large fixed frequency superconducting processors and present strategies towards tailoring the noise for error mitigation. I will then discuss our recent progress towards experimental implementations of zero noise extrapolation on a 65 qubit processor.
