Optimal tests of genuine multipartite nonlocality
New Journal of Physics, 2022 We propose an optimal and efficient numerical test for witnessing genuine multipartite nonlocality based on a geometric approach. In particular, we consider two non-equivalent models of local hidden variables, namely the Svetlichny and the no-signaling ...

Quantum Reports, 2023 In this work, an alternative attempt to motivate the Many-Worlds Interpretation (MWI) is undertaken. The usual way of arguing for MWI mostly revolves around how it might solve the measurement problem in a more straightforward and concise manner than ...

The Analogue of Bohm-Bell Processes on a Graph [PDF]
, 2005 Bohm-Bell processes, of interest in the foundations of quantum field theory, form a class of Markov processes $Q_t$ generalizing in a natural way both Bohm's dynamical system in configuration space for nonrelativistic quantum mechanics and Bell's jump ...

Quantum Superpositions of Causal Structures
Critical Hermeneutics, 2020 This presentation provides a non-technical overview of the notion of quantum superposition of causal structures, of its applications, and of its proposed physical realizations.

Geometry and structure of quantum phase space
, 2015 The application of geometry to physics has provided us with new insightful information about many physical theories such as classical mechanics, general relativity, and quantum geometry (quantum gravity).

Experiment Investigating the Connection between Weak Values and Contextuality [PDF]
, 2016 Weak value measurements have recently given rise to a large interest for both the possibility of measurement amplification and the chance of further quantum mechanics foundations investigation.

Categorical Probabilistic Theories [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 We present a simple categorical framework for the treatment of probabilistic theories, with the aim of reconciling the fields of Categorical Quantum Mechanics (CQM) and Operational Probabilistic Theories (OPTs).

Locality, Realism, Ergodicity and Randomness in Bell’s Experiment
Entropy, 2023 Assuming that there is no way of sending signals propagating faster than light and that free will exists, the loophole-free observed violation of Bell’s inequalities demonstrates that at least one of three fundamental hypotheses involved in the ...

Foundations of Quaternion Quantum Mechanics
Journal of Mathematical Physics, 1962 A new kind of quantum mechanics using inner products, matrix elements, and coefficients assuming values that are quaternionic (and thus noncommutative) instead of complex is developed. This is the most general kind of quantum mechanics possessing the same kind of calculus of assertions as conventional quantum mechanics.

Towards Relational Foundations for Spacetime Quantum Physics
UniverseRovelli’s relational interpretation of quantum mechanics tells us that the description of a system in the formalism of quantum mechanics is not an absolute but is relative to the observer itself.
