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 ...

Quantum social networks
(IOP Science, 2012)
We introduce a physical approach to social networks (SNs) in which each actor is characterized by a yes–no test on a physical system. This allows us to consider SNs beyond those originated by interactions based on ...

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 ...

The use of changes in small coastal Atlantic brooks in southwestern Europe as indicators of anthropogenic and climatic impacts over the last 400 years
(Springer Nature, 2015)
Unlike other aquatic continental ecosystems such as lakes, small coastal brooks have not been used as indicators of anthropogenic or climatic impacts. Our study addresses reconstructing the evolution of coastal brooks in ...

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 ...

Basic exclusivity graphs in quantum correlations
(American Physical Society, 2013)
A fundamental problem is to understand why quantum theory only violates some noncontextuality (NC) inequalities and identify the physical principles that prevent higher-than-quantum violations. We prove that quantum ...

Quantum nonlocality via local contextuality with qubit-qubit entanglement
(American Physical Society, 2016-04-28)
Quantum nonlocality can be revealed “via local contextuality” in qudit-qudit entangled systems with d > 2 , that is, through the violation of inequalities containing Alice-Bob correlations that admit a local description, ...

Quantum clock synchronization with a single qudit
(Nature Research, 2015-01-23)
Clock synchronization for nonfaulty processes in multiprocess networks is indispensable for a variety of technologies. A reliable system must be able to resynchronize the nonfaulty processes upon some components failing ...

Device-independent tests of structures of measurement incompatibility
(American Physical Society, 2019-10-31)
In contrast with classical physics, in quantum physics some sets of measurements are incompatible in the sense that they cannot be performed simultaneously. Among other applications, incompatibility allows for contextuality ...

Experimental demonstration of the connection between quantum contextuality and graph theory
(American Physical Society, 2016-07-20)
We report a method that exploits a connection between quantum contextuality and graph theory to reveal any form of quantum contextuality in high-precision experiments. We use this technique to identify a graph which ...
