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 ...

Realism and objectivism in quantum mechanics [PDF]
, 2012 The present study attempts to provide a consistent and coherent account of what the world could be like, given the conceptual framework and results of contemporary quantum theory. It is suggested that standard quantum mechanics can, and indeed should, be

, 2023 We present two results on the subject of quantum contextuality and cohomology, and non-locality and quantum advantage with shallow circuits. Abramsky et al. showed that a range of examples of quantum contextuality is detected by a cohomological invariant

Contextuality in foundations and quantum computation [PDF]
, 2020 Contextuality is a key concept in quantum theory. We reveal just how important it is by demonstrating that quantum theory builds on contextuality in a fundamental way: a number of key theorems in quantum foundations can be given a unifi ed presentation ...

Causation, decision theory, and Bell's theorem: a quantum analogue of the Newcomb problem [PDF]
, 2009 I apply some of the lessons from quantum theory, in particular from Bell's theorem, to a debate on the foundations of decision theory and causation. By tracing a formal analogy between the basic assumptions of Causal Decision Theory (CDT)---which was ...

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

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.

Separability, Contextuality, and the Quantum Frame Problem
International Journal of Theoretical Physics, 2023 We study the relationship between assumptions of state separability and both preparation and measurement contextuality, and the relationship of both of these to the frame problem, the problem of predicting what does not change in consequence of an action. We state a quantum analog of the latter and prove its undecidability. We show how contextuality is

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-

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 ...
