Atom graph, partial Boolean algebra and quantum contextuality [PDF]
Quantum Information ProcessingPartial Boolean algebra underlies the quantum logic as an important tool for quantum contextuality. We propose the notion atom graphs to reveal the graph structure of partial Boolean algebra for finite dimensional quantum systems by proving that (i) the ...

On the Quantum-like Contextuality of Ambiguous Phrases [PDF]
, 2021 Language is contextual as meanings of words are dependent on their contexts. Contextuality is, concomitantly, a well-defined concept in quantum mechanics where it is considered a major resource for quantum computations.

Using Quantum Cheshire Cats to explore Contextuality and Quantum Coherence [PDF]
We analyse the quantum Cheshire cat using contextuality theory. The results shed a surprising new light on the relation between quantum paradoxes, weak values, and contextuality, a key resource for quantum computing.© 2024 The Author ...

CONTEXTUAL DETERMINISTIC QUANTUM MECHANICS [PDF]
International Journal of Modern Physics B, 2000 We present a simple proof of quantum contextuality for a spinless particle with a one-dimensional configuration space. We then discuss how the maximally realistic deterministic quantum mechanics recently constructed by this author and V. Singh can be applied to different contexts.

Contextuality in infinite one-dimensional translation-invariant local Hamiltonians
npj Quantum Information, 2022 In recent years there has been a growing interest in treating many-body systems as Bell scenarios, where lattice sites play the role of distant parties and only near-neighbor statistics are accessible. We investigate contextuality arising from three Bell

Revealing universal quantum contextuality through communication games [PDF]
Scientific Reports, 2019 An ontological model of an operational theory is considered to be universally noncontextual if both preparation and measurement noncontextuality assumptions are satisfied in that model.

Measurement contextuality and Planck’s constant
New Journal of Physics, 2018 Contextuality is a necessary resource for universal quantum computation and non-contextual quantum mechanics can be simulated efficiently by classical computers in many cases. Orders of Planck’s constant, ℏ, can also be used to characterize the classical-

Equivariant simplicial distributions and quantum contextuality [PDF]
, 2023 We introduce an equivariant version of contextuality with respect to a symmetry group, which comes with natural applications to quantum theory. In the equivariant setting, we construct cohomology classes that can detect contextuality.

Non-Classical Correlations in n-Cycle Setting
Entropy, 2019 Quantum communication and quantum computation form the two crucial facets of quantum information theory. While entanglement and its manifestation as Bell non-locality have been proved to be vital for communication tasks, contextuality (a generalisation ...
