Efficient Eigenstate Preparation in an Integrable Model with Hilbert Space Fragmentation
Roberto Ruiz, Alejandro Sopena, Balázs Pozsgay +1
We consider the preparation of all the eigenstates of spin chains using quantum circuits. It is known that generic eigenstates of free-fermionic spin chains can be prepared with ci…
Bethe Ansatz, Quantum Circuits, and the F-basis
Roberto Ruiz, Alejandro Sopena, Esperanza López +2
The Bethe Ansatz is a method for constructing exact eigenstates of quantum-integrable spin chains. Recently, deterministic quantum algorithms, referred to as "algebraic Bethe circu…
Comparative study of quantum error correction strategies for the heavy-hexagonal lattice
César Benito, Esperanza López, Borja Peropadre +1
Topological quantum error correction is a milestone in the scaling roadmap of quantum computers, which targets circuits with trillions of gates that would allow running quantum alg…
