Variational noise mitigation in quantum circuits: the case of Quantum Fourier Transform
Rafael Gómez-Lurbe, Alexander Bernal, Armando Pérez +2
We propose using variational quantum algorithms (VQAs) to simulate established quantum algorithms under realistic noise conditions, aiming to surpass the fidelity of theoretical ci…
Maximal Clauser-Horne-Shimony-Holt violation for qubit-qudit states
Alexander Bernal, J. Alberto Casas, Jesus M. Moreno
We evaluate the maximal Clauser-Horne-Shimony-Holt (CHSH) violation for a generic (typically mixed) qubit-qudit state, obtaining easily computable expressions in arbitrary qudit di…
Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
Practical Criteria for Entanglement and Nonlocality in Systems with Additive Observables
Alexander Bernal, J. Alberto Casas, Juan Falceto
For general bipartite mixed states, a sufficient and necessary mathematical condition for certifying entanglement and/or (Bell) non-locality remains unknown. In this paper, we exam…
Nonlocality under Jaynes-Cummings evolution: beyond pseudospin operators
Alexander Bernal, J. Alberto Casas, Jesus M. Moreno
We re-visit the generation and evolution of (Bell) nonlocality in hybrid scenarios whose dynamics is determined by the Jaynes-Cummings Hamiltonian, a relevant example of which is t…
