Forecasting Quantum Observables: A Compressed Sensing Approach with Performance Guarantees
Víctor Valls, Albert Akhriev, Olatz Sanz Larrarte +5
Data-driven extrapolation methods aim to extend the dynamics of quantum observables from measurements, but they often lack guarantees on prediction accuracy. We introduce a framewo…

Quantum CSS Duadic and Triadic Codes: New Insights and Properties
Reza Dastbasteh, Olatz Sanz Larrarte, Josu Etxezarreta Martinez +3
In this study, we investigate the construction of quantum CSS duadic codes with dimensions greater than one. We introduce a method for extending smaller splittings of quantum duadi…

Comment on "Recovering noise-free quantum observables"
Josu Etxezarreta Martinez, Olatz Sanz Larrarte, Javier Oliva del Moral +2
Zero-noise extrapolation (ZNE) stands as the most widespread quantum error mitigation technique in order to aim the recovery of noise-free expectation values of observables of inte…
