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.

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 ...

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.

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”.

State-independent test of quantum contextuality with either single photons or coherent light
npj Quantum Information, 2021 Contextuality is a phenomenon at the heart of quantum mechanics different from classical behavior and has been recently identified as a resource in quantum information processing. Experimental demonstration of contextuality is thus an important goal.

Revealing universal quantum contextuality through communication games. [PDF]
Sci Rep, 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.

Contextuality in Collective Intelligence: Not There Yet [PDF]
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 ...
