The Extended Bloch Representation of Quantum Mechanics. Explaining Superposition, Interference and Entanglement Vrije Universiteit Brussel
Using abstract elastic membranes to learn about quantum measurements Vrije Universiteit Brussel
The objectives of the Center Leo Apostel for Interdisciplinary Studies were summarized by his creator as: interdisciplinarity, construction of world views and broad dissemination of scientific knowledge. In compliance with the third of these objectives, we provide a rigorous but accessible popular science version of a research article published by Aerts and Sassoli de Bianchi (Ann Phys 351:975–1025, 2014), where an extended version of the ...
Do Spins Have Directions? Vrije Universiteit Brussel
The standard Bloch sphere representation has been recently generalized to describe not only systems of arbitrary dimension, but also their measurements, in what has been called the extended Bloch representation of quantum mechanics. This model, which offers a solution to the longstanding measurement problem, is based on the hidden-measurement interpretation of quantum mechanics, according to which the Born rule results from our lack of ...
Many-Measurements or Many-Worlds? A Dialogue Vrije Universiteit Brussel
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 ...
The GTR-model: A universal framework for quantum-like measurements. Vrije Universiteit Brussel
THE GTR-MODEL Vrije Universiteit Brussel
We present a very general geometrico-dynamical description of physical or more abstract entities, called the general tension-reduction (GTR) model, where not only states, but also measurement-interactions can be represented, and the associated outcome probabilities calculated. Underlying the model is the hypothesis that indeterminism manifests as a consequence of unavoidable fluctuations in the experimental context, in accordance with the ...
