Identification and optimization of accurate spin models for Fermi-Hubbard ladders using matrix product states
Andoni Agirre, Thomas Frederiksen, Geza Giedke +1
Open-shell nanographenes offer a controlled setting to study correlated magnetism emerging from -electron systems. Here, we study non-bipartite Fermi-Hubbard ladders describing…

A Monte Carlo Tree Search approach to QAOA: finding a needle in the haystack
Andoni Agirre, Evert Van Nieuwenburg, Matteo M. Wauters
The search for quantum algorithms to tackle classical combinatorial optimization problems has long been one of the most attractive yet challenging research topics in quantum comput…
