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 ...

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, ...

Revisiting five decades of 234Th data: a comprehensive global oceanic compilation
(Copernicus Publications, 2022)
We present here a global oceanic compilation of 234Th measurements that collects results from researchers and laboratories over a period exceeding 50 years. The origin of the 234Th sampling in the ocean goes back to 1967, ...

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 ...

Irreducible magic sets for n-Qubit systems
(Physical Review Letters, 2022-11-07)
Magic sets of observables are minimal structures that capture quantum state-independent advantage for systems of n ≥ 2 qubits and are, therefore, fundamental tools for investigating the interface between classical and ...

Noncontextual wirings
(American Physical Society, 2018-03-29)
Contextuality is a fundamental feature of quantum theory necessary for certain models of quantum computation and communication. Serious steps have therefore been taken towards a formal framework for contextuality as an ...

Multidimensional entanglement generation with multicore optical fibers
(American Physical Society, 2021-03-09)
Trends in photonic quantum information follow closely the technical progress in classical optics and telecommunications. In this regard, advances in multiplexing optical communications channels have also been pursued for ...

Experimental test of quantum correlations from Platonic graphs
(Optica Publishing Group, 2018-05-29)
Great effort has been made in the investigation of contextual correlations between compatible observables due to their both fundamental and practical importance. The graph-theoretic approach to correlate events has been ...
