Hybrid quantum-classical analog simulation of two-dimensional Fermi-Hubbard models with neutral atoms
Sergi Julià-Farré, Antoine Michel, Christophe Domain +11
We experimentally study the two-dimensional Fermi-Hubbard model using a Rydberg-based quantum processing unit in the analog mode. Our approach avoids encoding directly the original…

Pulse-based optimization of quantum many-body states with Rydberg atoms in optical tweezer arrays
Kazuma Nagao, Sergi Julià-Farré, Joseph Vovrosh +2
We explore a pulse-based variational quantum eigensolver (VQE) algorithm for Rydberg atoms in optical tweezer arrays and evaluate its performance on prototypical quantum spin model…

Topological stripe state in an extended Fermi-Hubbard model
Sergi Julià-Farré, Lorenzo Cardarelli, Maciej Lewenstein +2
Interaction-induced topological systems have attracted a growing interest for their exotic properties going beyond the single-particle picture of topological insulators. In particu…
