Cavity-induced switching between Bell-state textures in a quantum dot
S. S. Beltrán-Romero, F. J. Rodríguez, L. Quiroga +1
Nanoscale quantum dots in microwave cavities can be used as a laboratory for exploring electron-electron interactions and their spin in the presence of quantized light and a magnet…
Experimental validation of the Kibble-Zurek Mechanism on a Digital Quantum Computer
Santiago Higuera-Quintero, Ferney J. Rodríguez, Luis Quiroga +1
The Kibble-Zurek mechanism (KZM) captures the essential physics of nonequilibrium quantum phase transitions with symmetry breaking. KZM predicts a universal scaling power law for t…
Ladder of Loschmidt anomalies in the deep strong-coupling regime of a qubit-oscillator system
J. M. Betancourt, F. J. Rodríguez, L. Quiroga +1
We uncover a remarkably regular array of singularity-like structures within the deep strong-coupling limit of qubit-oscillator (e.g. light-matter) systems described by the quantum…
Rényi Entropy Singularities as Signatures of Topological Criticality in Coupled Photon-Fermion Systems
F. P. M. Méndez-Córdoba, J. J. Mendoza-Arenas, F. J. Gómez-Ruiz +3
We show that the topological phase transition for a Kitaev chain embedded in a cavity can be identified by measuring experimentally accessible photon observables such as the Fano f…
Enhancing violations of Leggett-Garg inequalities in nonequilibrium correlated many-body systems by interactions and decoherence
J. J. Mendoza-Arenas, F. J. Gómez-Ruiz, F. J. Rodríguez +1
We identify different schemes to enhance the violation of Leggett-Garg inequalities in open many-body systems. Considering a nonequilibrium archetypical setup of quantum transport,…
Chapter: Vulnerability of Quantum Information Systems to Collective Manipulation
Fernando J. Gómez-Ruiz, Ferney J. Rodríguez, Luis Quiroga +1
The highly specialist terms `quantum computing' and `quantum information', together with the broader term `quantum technologies', now appear regularly in the mainstream media. Whil…
