Chiral Majorana interference as a source of quantum entanglement
(American Physical Society, 2018)
Two-particle Hanbury Brown-Twiss interferometry with chiral Majorana modes produces maximally entangled electron-hole pairs. We promote the electron-hole quantum number to an interferometric degree of freedom and complete ...

Parametric analysis of the edge capacitance of uniform slots and application to frequency-variation permittivity sensors
(MDPI, 2021-07-29)
This paper presents a parametric analysis relative to the effects of the dielectric constant of the substrate, substrate thickness and slot width on the edge capacitance of a slot-based resonator. The interest is to find ...

Self-testing of a single quantum system from theory to experiment
(Nature Research, 2023-10-19)
Self-testing allows one to characterise quantum systems under minimal assumptions. However, existing schemes rely on quantum nonlocality and cannot be applied to systems that are not entangled. Here, we introduce a robust ...

Research facilities and highlights at the Centro Nacional de Aceleradores (CNA)
(Springer, 2021)
The Centro Nacional de Aceleradores is a user-oriented accelerator facility in Seville, Spain. Its main facilities are a 3 MV tandem accelerator, an 18 MeV proton Cyclotron, a tandetron used for AMS, a compact accelerator ...

Maximum nonlocality in the (3,2,2) scenario
(American Physical Society, 2016-12-27)
We identify the simplest combinations of entanglement and incompatibility giving the maximum quantum violation for each of the 46 classes of tight Bell inequalities for the (3,2,2) scenario, i.e., three parties, two ...

Bell nonlocality with intensity information only
(American Physical Society, 2020-09-01)
We address the problem of detecting bipartite Bell nonlocality whenever the only experimental information are the intensities produced in each run of the experiment by an unknown number of particles. We point out that this ...

Significant loophole-free test of Kochen-Specker contextuality using two species of atomic ions
(American Association for the Advancement of Science, 2022-02-09)
Quantum measurements cannot be thought of as revealing preexisting results, even when they do not disturb any other measurement in the same trial. This feature is called contextuality and is crucial for the quantum advantage ...

Monolithic integration of graphene in SiC radiation sensors for harsh-environment applications
(Trans Tech Publications, 2022)
Due to their low leakage current, low noise levels, high thermal conductivity, and potential radiation hardness, SiC devices offer various advantages over Si devices in certain applications. As a result, they are being ...

Geometric driving of two-level quantum systems
(American Physical Society, 2020)
We investigate a class of cyclic evolutions for driven two-level quantum systems (effective spin 1/2) with a particular focus on the geometric characteristics of the driving and their specific imprints on the quantum ...

Geometric vector potentials from nonadiabatic spin dynamics
(American Physical Society, 2017-07-27)
We propose a theoretical framework that captures the geometric vector potential emerging from the nonadiabatic spin dynamics of itinerant carriers subject to arbitrary magnetic textures. Our approach results in a series ...
