Single-Photon Quantum Contextuality on a Chip [PDF]
ACS Photonics, 2017 In classical physics, properties of objects exist independently of the context, i.e., whether and how measurements are performed. Quantum physics showed this assumption to be wrong, and that Nature is indeed “contextual”.

Quantum Contextuality with Stabilizer States [PDF]
Entropy, 2013 The Pauli groups are ubiquitous in quantum information theory because of their usefulness in describing quantum states and operations and their readily understood symmetry properties.

Contextual quantum metrology [PDF]
npj Quantum Information, 2023 We demonstrate that the contextuality of measurement selection can enhance the precision of quantum metrology with a simple linear optical experiment. Contextuality is a nonclassical property known as a resource for various quantum information processing

Contextuality in Collective Intelligence: Not There Yet
Entropy, 2023 Type I contextuality or inconsistent connectedness is a fundamental feature of both the classical as well as the quantum realms. Type II contextuality (true contextuality or CHSH-type contextuality) is frequently asserted to be specific to the quantum ...

Golay codes and quantum contextuality [PDF]
Physical Review A, 2022 It is shown that the codewords of the binary and ternary Golay codes can be converted into rays in RP(23) and RP(11) that provide proofs of the Kochen-Specker theorem in real state spaces of dimension 24 and 12, respectively.

Quantum Contextuality Provides Communication Complexity Advantage. [PDF]
Physical Review Letters, 2022 Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement.

Experimental Test of High-Dimensional Quantum Contextuality Based on Contextuality Concentration. [PDF]
Physical Review Letters, 2022 Contextuality is a distinctive feature of quantum theory and a fundamental resource for quantum computation. However, existing examples of contextuality in high-dimensional systems lack the necessary robustness required in experiments.

Relational Quantum Mechanics and Contextuality [PDF]
Foundations of Physics, 2023 This paper discusses the question of stable facts in relational quantum mechanics (RQM). I examine how the approach to quantum logic in the consistent histories formalism can be used to clarify what infomation about a system can be shared between ...

Separability, Contextuality, and the Quantum Frame Problem [PDF]
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.

Contextuality as a Precondition for Quantum Entanglement [PDF]
Physical Review LettersQuantum theory features several phenomena which can be considered as resources for information processing tasks. Some of these effects, such as entanglement, arise in a nonlocal scenario, where a quantum state is distributed between different parties ...
