# Proposed Experimental Tests of the Bell-Kochen-Specker Theorem

@article{Cabello1998ProposedET, title={Proposed Experimental Tests of the Bell-Kochen-Specker Theorem}, author={Ad{\'a}n Cabello and Guillermo Garc{\'i}a-Alcaine}, journal={Physical Review Letters}, year={1998}, volume={80}, pages={1797-1799} }

For a two-particle two-state system, sets of compatible propositions exist for which quantum mechanics and noncontextual hidden-variable theories make conflicting predictions for every individual system whatever its quantum state. This permits a simple all-or-nothing state-independent experimental verification of the Bell-Kochen-Specker theorem.

We present a simple experimental scheme which can be used to demonstrate an all-or-nothing-type contradiction between noncontextual hidden variables and quantum mechanics. The scheme, which is…

### Proposed Direct Test of Quantum Contextuality

- Physics

Quantum contextually can be directly tested by an Einstein-Podolsky-Rosen-type experiment of two spin one and higher particles in a singlet state. The two associated contexts are “interlinked” by a…

The noncontextuality of quantum mechanics can be directly tested by measuring two entangled particles with more than two outcomes per particle. The two associated contexts are 'interlinked' by common…

We present an experimental test of quantum contextuality by using two-photon product states. The experimental results show that the noncontextual hidden-variable theories are violated by nonentangled…

Using the spontaneous parametric down-conversion process in a type-I phase matching beta-barium-borate crystal as a single photon source, an all-or-nothing-type Kochen-Specker experiment is performed to verify whether noncontextual hidden variables or quantum mechanics is right.

### A state-independent test of the Kochen-Specker theorem

- Computer Science

A feasible Kochen–Specker experiment with single photons, whose goal is to submit noncontextual hidden-variable theories to nonstatistical, all-or-nothing tests, is proposed, which can deal with non-ideal detectors without invoking the fair sampling assumption.

### Quantum contextuality in a single-neutron optical experiment.

- PhysicsPhysical review letters

An experimental demonstration of quantum contextuality with neutrons is presented, which intended to exhibit a Kochen-Specker-like phenomenon, and results clearly violate the prediction of noncontextual theories.

A recent proposal to experimentally test quantum mechanics against noncontextual hidden-variable theories [Phys. Rev. Lett. 80, 1797 (1998)] is shown to be related with the smallest proof of the…

### State-independent experimental test of quantum contextuality

- PhysicsNature

Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.
