Extracting conformal data from Loschmidt echoes after critical quenches

Aleix Bou-Comas, Stefano Carignano, Sergio Cerezo-Roquebrún +2

Conformal field theory provides universal predictions for Loschmidt amplitudes following quenches from product states to critical Hamiltonians. Building on this observation, we dev…

Mesoscopic Regimes of Temporal Entanglement in Ergodic Quantum Systems

Sergio Cerezo-Roquebrún, Jan Thorben Schneider, Stefano Carignano +4

We study temporal correlations in interacting quantum systems through the influence functional of a half-infinite quantum Ising chain. Using Rényi entropies and temporal mutual inf…

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…

The Bethe Ansatz as a Quantum Circuit

Roberto Ruiz, Alejandro Sopena, Max Hunter Gordon +2

The Bethe ansatz represents an analytical method enabling the exact solution of numerous models in condensed matter physics and statistical mechanics. When a global symmetry is pre…

Thermal masses and trapped-ion quantum spin models: a self-consistent approach to Yukawa-type interactions in the model

Pablo Viñas Martínez, Esperanza López, Alejandro Bermudez

The quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins, which are encoded in the internal ele…
