Noise-robust preparation contextuality shared between any number of observers via unsharp measurements [PDF]
Quantum, 2021 Multiple observers who independently harvest nonclassical correlations from a single physical system share the system's ability to enable quantum correlations.

Contextuality, coherences, and quantum Cheshire cats [PDF]
New Journal of Physics, 2023 We analyse the quantum Cheshire cat using contextuality theory, to see if this can tell us anything about how best to interpret this paradox. We show that this scenario can be analysed using the relation between three different measurements, which seem ...

Quantum measurements and contextuality [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 In quantum physics, the term ‘contextual’ can be used in more than one way. One usage, here called ‘Bell contextual’ since the idea goes back to Bell, is that if A , B and C are three quantum observables, with A compatible (i.e. commuting) with

Contextual logic for quantum systems [PDF]
Journal of Mathematical Physics, 2004 In this work we build a quantum logic that allows us to refer to physical magnitudes pertaining to different contexts from a fixed one without the contradictions with quantum mechanics expressed in no-go theorems. This logic arises from considering a sheaf over a topological space associated with the Boolean sublattices of the ortholattice of closed ...

Popper, Bohr et la contextualité de la mécanique quantique
Philosophia Scientiæ, 2021 During his intellectual life, Karl Popper blamed Niels Bohr for defending subjectivist theses about Quantum Mechanics and for introducing the concept of subject in physics. But Popper’s accusation contradicts Bohr’s texts.

Contextuality as a resource for models of quantum computation on qubits [PDF]
, 2017 A central question in quantum computation is to identify the resources that are responsible for quantum speed-up. Quantum contextuality has been recently shown to be a resource for quantum computation with magic states for odd-prime dimensional qudits ...

Entropic Test of Quantum Contextuality [PDF]
Physical Review Letters, 2012 We study the contextuality of a three-level quantum system using classical conditional entropy of measurement outcomes. First, we analytically construct the minimal configuration of measurements required to reveal contextuality. Next, an entropic contextual inequality is formulated, analogous to the entropic Bell inequalities derived by Braunstein and ...

Causation does not explain contextuality [PDF]
Quantum, 2018 Realist interpretations of quantum mechanics presuppose the existence of elements of reality that are independent of the actions used to reveal them. Such a view is challenged by several no-go theorems that show quantum correlations cannot be explained ...
