Improving Quantum Sensors Subject to Correlated Noise Using Zero-noise Extrapolation

ORAL

Abstract

We apply zero-noise extrapolation (ZNE), a well-known error mitigation technique for noisy, intermediate scale quantum computers, to the domain of quantum sensing. We evaluate its effectiveness for the prototypical examples of DC and AC magnetometry using entangled qubit sensors. We focus on the realistic case of spatiotemporally correlated noise, employing the filter function formalism to analyze the impact on sensor performance. Our results suggest that ZNE is a viable method for enhancing quantum sensing capabilities in the presence of highly-correlated noise.
