• Title: Are Words the Quanta of Human Language? Extending the Domain of Quantum Cognition
• Authors: Diederik Aerts and Lester Beltran
• Abstract summary: We show that quantization is present in human cognition in the form of the words behaving as quanta of human language. We investigate this entanglement, compute the von Neumann entropy and the amount of non purity of the density matrices of the words. We interpret these results in terms of the prospect of developing a quantum-inspired thermodynamics for the cultural layer of human society.

• Abstract: Quantum structures were identified as relevant for describing situations occurring in human cognition in the domain of quantum cognition and were also fruitfully used in information retrieval and natural language processing in the domain of quantum information theory. In the present article, we build on recent prior work and show that additionally to the already identified quantum structures also quantization is present in human cognition. It appears in the form of the words behaving as quanta of human language, very analogous to how photons behave as quanta of electromagnetic radiation. We illustrate this by showing on an example text that Bose-Einstein statistics provides a perfect model while Maxwell-Boltzmann statistics is totally inadequate. Like the indistinguishability of quantum particles introduces a specific form of entanglement this also happens with words. We investigate this entanglement, compute the von Neumann entropy and the amount of non purity of the density matrices of the words and note that non-locality occurs spontaneously. We interpret these results in terms of the prospect of developing a quantum-inspired thermodynamics for the cultural layer of human society, based on a statistical analysis similar to what we propose in this article.

• Contextual unification of classical and quantum physics [0.0]
  We develop the idea that the usual formalism of quantum mechanics stops working when countable infinities of particles are encountered. This is because the dimension of the corresponding Hilbert space becomes uncountably infinite, leading to the loss of unitary equivalence. We show that it provides a natural way to describe the "Heisenberg cut", as well as a unified mathematical model including both quantum and classical physics.

• Assessing randomness with the aid of quantum state measurement [0.0]
  We consider the production of random bits from polarization measurements on photons. We prepare photons in different nonentangled and entangled states, and measure these states tomographically. We use the information about the quantum state to determine, in terms of the min-entropy, the minimum amount of randomness produced from a given photon state by different bit-generating measurements.
