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…

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…

Global restrictions under local state discrimination
Carles Roch I Carceller, Alexander Bernal
We investigate how local distinguishability can restrict global properties of bi-partite states. We begin exploring how non-locality becomes limited by optimal local state discrimi…
