Quantum Contextuality and Indeterminacy [PDF]
Entropy, 2020 The circumstances of measurement have more direct significance in quantum than in classical physics, where they can be neglected for well-performed measurements.

Chromatic Quantum Contextuality [PDF]
EntropyChromatic quantum contextuality is a criterion of quantum nonclassicality based on (hyper)graph coloring constraints. If a quantum hypergraph requires more colors than the number of outcomes per maximal observable (context), it lacks a classical ...

Statistical Signatures of Quantum Contextuality [PDF]
EntropyQuantum contextuality describes situations where the statistics observed in different measurement contexts cannot be explained by a measurement of the independent reality of the system. The most simple case is observed in a three-dimensional Hilbert space, with five different measurement contexts related to each other by shared measurement outcomes ...

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.

Single-Photon Quantum Contextuality on a Chip. [PDF]
ACS Photonics, 2017 In classical physics, properties of the objects exist independently on the context, i.e. whether and how measurements are performed. Quantum physics showed this assumption to be wrong and that Nature is indeed "contextual". Contextuality has been observed in the simplest physical systems such as single particles, and plays fundamental roles in quantum ...

Contextuality in Classical Physics and Its Impact on the Foundations of Quantum Mechanics
Entropy, 2021 It is shown that the hallmark quantum phenomenon of contextuality is present in classical statistical mechanics (CSM). It is first shown that the occurrence of contextuality is equivalent to there being observables that can differentiate between pure and

Quantum, 2023 Quantum contextual sets have been recognized as resources for universal quantum computation, quantum steering and quantum communication. Therefore, we focus on engineering the sets that support those resources and on determining their structures and ...

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 ...

Simplicial quantum contextuality [PDF]
Quantum, 2023 We introduce a new framework for contextuality based on simplicial sets, combinatorial models of topological spaces that play a prominent role in modern homotopy theory.

Homotopical approach to quantum contextuality [PDF]
Quantum, 2020 We consider the phenomenon of quantum mechanical contextuality, and specifically parity-based proofs thereof. Mermin’s square and star are representative examples.
