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…
Witnessing entanglement in trapped-ion quantum error correction under realistic noise
Andrea Rodriguez-Blanco, Farid Shahandeh, Alejandro Bermudez
Quantum Error Correction (QEC) exploits redundancy by encoding logical information into multiple physical qubits. In current implementations of QEC, sequences of non-perfect two-qu…
Fermion production at the boundary of an expanding universe: a cold-atom gravitational analogue
Carlos Fulgado-Claudio, Jose M. Sánchez Velázquez, Alejandro Bermudez
We study the phenomenon of cosmological particle production of Dirac fermions in a Friedman-Robertson-Walker spacetime, focusing on a (1+1)-dimensional case in which the evolution…
Suppressing Amplitude Damping in Trapped Ions: Discrete Weak Measurements for a Non-unitary Probabilistic Noise Filter
Andrea Rodriguez-Blanco, K. Birgitta Whaley, Alejandro Bermudez
The idea of exploiting maximally-entangled states as a resource lies at the core of several modalities of quantum information processing, including secure quantum communication, qu…
Topological chiral currents in the Gross-Neveu model extension
E. Tirrito, M. Lewenstein, A. Bermudez
We unveil an interesting connection of Lorentz-violating quantum field theories, studied in the context of the standard model extension, and Hubbard-type models of topological crys…
Large- Chern insulators: lattice field theory and quantum simulation approaches to correlation effects in the quantum anomalous Hall effect
L. Ziegler, E. Tirrito, M. Lewenstein +2
Four-Fermi quantum field theories in (2+1) dimensions lie among the simplest models in high-energy physics, the understanding of which requires a non-perturbative lattice formulati…
