Noise remains a fundamental obstacle to reliable quantum software โ€” yet current models are often static, coarse, and misaligned with real system behaviour.

In this work, we introduceย ๐’๐’Š๐’—๐’† ๐’๐’๐’Š๐’”๐’† ๐’‡๐’Š๐’๐’ˆ๐’†๐’“๐’‘๐’“๐’Š๐’๐’•๐’Š๐’๐’ˆ, a lightweight and empirical approach to characterising noisy quantum systems.

Our key idea: โ†’ leverageย ๐’„๐’๐’‚๐’”๐’”๐’Š๐’„๐’‚๐’ ๐’”๐’‰๐’‚๐’…๐’๐’˜ ๐’•๐’†๐’„๐’‰๐’๐’Š๐’’๐’–๐’†๐’”ย to build compact, updatable fingerprints of noise โ†’ enableย efficient comparison of quantum states and platformsย (e.g., Qiskit vs Cirq) โ†’ support practical workflows forย ๐’•๐’†๐’”๐’•๐’Š๐’๐’ˆ, ๐’…๐’†๐’ƒ๐’–๐’ˆ๐’ˆ๐’Š๐’๐’ˆ, and ๐’„๐’“๐’๐’”๐’”-๐’‘๐’๐’‚๐’•๐’‡๐’๐’“๐’Ž ๐’—๐’‚๐’๐’Š๐’…๐’‚๐’•๐’Š๐’๐’

We implement this vision inย SIMSHADOW, showing that fingerprints: โ€ข capture structured, interpretable noise patterns โ€ข reveal systematic cross-platform discrepancies โ€ข correlate with observable divergences in program outputs

More broadly, this work bridgesย ๐’’๐’–๐’‚๐’๐’•๐’–๐’Ž ๐’Š๐’๐’‡๐’๐’“๐’Ž๐’‚๐’•๐’Š๐’๐’ ๐’•๐’‰๐’†๐’๐’“๐’šย andย ๐’”๐’๐’‡๐’•๐’˜๐’‚๐’“๐’† ๐’•๐’†๐’”๐’•๐’Š๐’๐’ˆ, moving toward more reliable and portable quantum software systems.Congratulations Elena, Karine, Sophie, Mohammad!Faculty of Natural, Mathematical & Engineering SciencesCongratulations, Avner!
