Toward Quantum Utility in Correlated Topological Matter: Variational Preparation of Fractional Quantum Hall Manifolds
Sergio F. Expósito, Unai Aseginolaza, Raúl Guerrero-Avilés +3
We investigate the use of variational quantum algorithms to prepare and characterize fractional quantum Hall states on near-term quantum processors. Focusing on the Laughli…
A Useful Metric for the NISQ Era: Qubit Error Probability and Its Role in Zero Noise Extrapolation
Nahual Sobrino, Unai Aseginolaza, Joaquim Jornet-Somoza +1
Accurate assessment and management of errors is indispensable for extracting useful results from noisy intermediate-scale quantum (NISQ) devices. In this work, we propose the qubit…
Strong anharmonicity and high thermoelectric efficiency in high temperature SnS from first-principles
Unai Aseginolaza, Raffaello Bianco, Lorenzo Monacelli +5
SnS and SnSe are isoelectronic materials with a common phase diagram. Recently, SnSe was found to be the most efficient intrinsic thermoelectric material in its high-temperature Cm…
Phonon Collapse and Second-Order Phase Transition in Thermoelectric SnSe
Unai Aseginolaza, Raffaello Bianco, Lorenzo Monacelli +5
Since 2014 the layered semiconductor SnSe in the high-temperature Cmcm phase is known to be the most efficient thermoelectric material. Making use of first-principles calculations…
