Arithmetic loophole in Bell's Theorem: Overlooked threat to entangled-state quantum cryptography Vrije Universiteit Brussel
an explicit counterexample shows that a new class of local realistic models, based on generalized arithmetic and calculus, can exactly reconstruct rotationally symmetric quantum probabilities typical of
two-electron singlet states. Observable probabilities are consistent with the usual arithmetic employed
by macroscopic ...
Entanglement in Cognition violating Bell Inequalities Beyond Cirel'son's Bound Vrije Universiteit Brussel
We present the results of two tests where a sample of human participants were asked to make judgements about the conceptual combinations The Animal Acts and The Animal eats the Food. Both tests significantly violate the Clauser-Horne-Shimony-Holt version of Bell inequalities (‘CHSH inequality’), thus exhibiting manifestly non-classical behaviour due to the meaning connection between the individual concepts that are combined. We then apply a ...

Spin and Wind Directions II: A Bell State Quantum Model Vrije Universiteit Brussel
In the first half of this two-part article (Aerts et al. in Found Sci. doi:10.1007/s10699-017-9528-9, 2017b), we analyzed a cognitive psychology experiment where participants were asked to select pairs of directions that they considered to be the best example of Two Different Wind Directions, and showed that the data violate the CHSH version of Bell’s inequality, with same magnitude as in typical Bell-test experiments in physics. In this ...

The Heart of an Image: Quantum Superposition and Entanglement in Visual Perception Vrije Universiteit Brussel
We analyse the way in which the principle that ‘the whole is greater than the sum of its parts’ manifests itself with phenomena of visual perception. For this investigation we use insights and techniques coming from quantum cognition, and more specifically we are inspired by the correspondence of this principle with the phenomenon of the conjunction effect in human cognition. We identify entities of meaning within artefacts of visual ...
