Entanglement as a Method to Reduce Uncertainty Vrije Universiteit Brussel
In physics, entanglement ‘reduces’ the entropy of an entity, because the (von Neumann) qentropy of, e.g., a composite bipartite entity in a pure entangled state is systematically lower than the entropy of the component sub-entities. We show here that this ‘genuinely non-classical reduction of entropy as a result of composition’ also holds whenever two concepts combine in human cognition and, more generally, it is valid in human culture. On ...
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 ...
The Entanglement of the Social Realm Vrije Universiteit Brussel
This paper presents the outline of an ontology of the social realm that aims to provide a new perspective to the study of social phenomena. It will be argued that in order to raise the impact of the social sciences, research should start from a new ontological discursive perspective. This implies that rather than dividing the social and psychological realm into different “disciplines”, the social and the psychological realm need to be ...

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 ...
The extended Bloch Representation of Entanglement and Measurement in Quantum Mechanics Vrije Universiteit Brussel
The quantum formalism can be completed by assuming that density operators also represent genuine states. An ‘extended Bloch representation’ (EBR) then results, in which not only the states but also the measurement-interactions can be described. Consequently, the Born rule can be obtained as an expression that quantifies the lack of knowledge about the measurement-interaction that is each time actualized, during a measurement. Entanglement can ...
