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…
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…
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…
Entanglement and entropy in multipartite systems: a useful approach
A. Bernal, J. A. Casas, J. M. Moreno
Quantum entanglement and quantum entropy are crucial concepts in the study of multipartite quantum systems. In this work we show how the notion of concurrence vector, re-expressed…
