The possibility to test experimentally the Bell-Kochen-Specker theorem is investigated critically, following the demonstrations by Meyer, Kent and Clifton-Kent that the predictions of quantum mechanics are indistinguishable (up to arbitrary precision) from those of a non-contextual model, and the subsequent debate to which extent these models are actually classical or non-contextual. The present analysis starts from a careful consideration these "finite-precision" approximations. A stronger… Expand

Contextuality under weak assumptions
The presence of contextuality in quantum theory was first highlighted by Bell, Kochen and Specker, who discovered that for quantum systems of three or more dimensions, measurements cannot be viewedExpand
An experimental test of noncontextuality without unphysical idealizations
This work shows how to devise tests that are free of idealizations that real experiments cannot achieve, namely noiseless measurements and exact operational equivalences, and performs a photonic implementation of one such test, ruling out noncontextual models with high confidence. Expand
A proof of the Kochen-Specker theorem can always be converted to a state-independent noncontextuality inequality
Quantum contextuality is one of the fundamental notions in quantum mechanics. Proofs of the Kochen-Specker theorem and noncontextuality inequalities are two means for revealing the contextualityExpand
Contextuality-by-Default Description of Bell Tests: Contextuality as the Rule and Not as an Exception
The violation of Bell inequalities and inconsistent connectedness may be explained using a contextual locally causal probabilistic model in which setting dependent variables describing measuring instruments are correctly incorporated and it is proved that this model does not restrict experimenters’ freedom of choice which is a prerequisite of science.

Necessary and Sufficient Conditions for an Extended Noncontextuality in a Broad Class of Quantum Mechanical Systems.
This work derives necessary and sufficient conditions for the existence of a maximally noncontextual description in a broad class of systems including Klyachko-Can-Binicioğlu-Shumvosky-type (KCBS), EPR-Bell-type, and Leggett-Garg-type systems. Expand
Testing classical and quantum theory with single photons
To date, quantum theory is the most successful physical theory that has been discovered. However, there is still the possibility that an inconsistency between experimental observations and theExpand
Contextuality without nonlocality in a superconducting quantum system
This work uses a superconducting qutrit with deterministic, binary-outcome readouts to violate a noncontextuality inequality while addressing the detection, individual-existence and compatibility loopholes, demonstrating the fitness ofsuperconducting quantum circuits for fault-tolerant quantum computation in surface-code architectures.

Recent Advances in Contextuality Tests
The field of quantum contextuality is approached through its close relation to Bell type nonlocal scenarios and some of the rapidly developing tests and experimental implementations are highlighted. Expand
Simple method for experimentally testing any form of quantum contextuality
Contextuality provides a unifying paradigm for nonclassical aspects of quantum probabilities and resources of quantum information. Unfortunately, most forms of quantum contextuality remainExpand
Demonstrating quantum contextuality of indistinguishable particles by a single family of noncontextuality inequalities
It is shown in a simple and systematic manner that with projective measurements alone, it is possible to demonstrate quantum contextuality for such systems of arbitrary Hilbert space dimensions, including those corresponding to a qubit. Expand


Non-contextuality, finite precision measurement and the Kochen-Specker theorem
Abstract Meyer originally raised the question of whether non-contextual hidden variable models can, despite the Kochen–Specker theorem, simulate the predictions of quantum mechanics to within anyExpand
State-independent experimental test of quantum contextuality
The question of whether quantum phenomena can be explained by classical models with hidden variables is the subject of a long-lasting debate. In 1964, Bell showed that certain types of classicalExpand
Quantum contextuality from a simple principle
In a recent article entitled "A simple explanation of the quantum violation of a fundamental inequality," Cabello proposes a condition on a class of probabilistic models that, he claims, gives theExpand
Contextuality for preparations, transformations, and unsharp measurements
The Bell-Kochen-Specker theorem establishes the impossibility of a noncontextual hidden variable model of quantum theory, or equivalently, that quantum theory is contextual. In this paper, anExpand
(Non-)Contextuality of Physical Theories as an Axiom
We show that the noncontextual inequality proposed by Klyachko et al. [Phys. Rev. Lett. 101, 020403 (2008)] belongs to a broader family of inequalities, one associated to each compatibility structureExpand
The Role of Bounded Memory in the Foundations of Quantum Mechanics
If quantum mechanics is correct and there is a finite upper bound for the speed of causal influences (e.g., the speed of light), then quantum mechanics is complete (i.e., it does not admit a moreExpand
Specker’s parable of the overprotective seer: A road to contextuality, nonlocality and complementarity
In 1960, the mathematician Ernst Specker described a simple example of nonclassical correlations, the counter-intuitive features of which he dramatized using a parable about a seer, who sets anExpand
The Bell–Kochen–Specker theorem
Abstract Meyer, Kent and Clifton (MKC) claim to have nullified the Bell–Kochen–Specker (Bell-KS) theorem. It is true that they invalidate Kochen and Specker's account of the theorem's physicalExpand
Simulating quantum mechanics by non-contextual hidden variables
No physical measurement can be performed with infinite precision. This leaves a loophole in the standard no-go arguments against non-contextual hidden variables. All such arguments rely on choosingExpand
Proposed experiment for testing quantum contextuality with neutrons.
We show that an experimental demonstration of quantum contextuality using 2 degrees of freedom of single neutrons based on a violation of an inequality derived from the Peres-Mermin proof of theExpand
