Contextuality and Wigner function negativity in qubit quantum computation [PDF]
, 2017 We describe a scheme of quantum computation with magic states on qubits for which contextuality is a necessary resource possessed by the magic states.

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 ...

Nonseparability, Potentiality and the Context-Dependence of Quantum Objects [PDF]
, 2007 Standard quantum mechanics undeniably violates the notion of separability that classical physics accustomed us to consider as valid. By relating the phenomenon of quantum nonseparability to the all-important concept of potentiality, we effectively ...

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

Randomness Expansion Secured by Quantum Contextuality [PDF]
Physical Review Applied, 2019 The output randomness from a random number generator can be certified by observing the violation of quantum contextuality inequalities based on the Kochen-Specker theorem.

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.

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-

Contextual Subspace Variational Quantum Eigensolver [PDF]
Quantum, 2021 We describe the contextual subspace variational quantum eigensolver (CS-VQE), a hybrid quantum-classical algorithm for approximating the ground state energy of a Hamiltonian. The approximation to the ground state energy is obtained as the sum of two contributions.

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 ...
