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 ...

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 ...

Conservation of information and the foundations of quantum mechanics
EPJ Web of Conferences, 2015 We review a recent approach to the foundations of quantum mechanics inspired by quantum information theory [1, 2]. The approach is based on a general framework, which allows one to address a large class of physical theories which share basic information ...

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.

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.

Discrete-event simulation of uncertainty in single-neutron experiments
Frontiers in Physics, 2014 A discrete-event simulation approach which provides a cause-and-effect description of manyexperiments with photons and neutrons exhibiting interference and entanglement is applied to a recentsingle-neutron experiment that tests (generalizations of ...

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 QUANTUM MECHANICS: DECOHERENCE AND INTERPRETATION [PDF]
International Journal of Modern Physics D, 2011 In this paper, we review Castagnino's contributions to the foundations of quantum mechanics. First, we recall his work on quantum decoherence in closed systems, and the proposal of a general framework for decoherence from which the phenomenon acquires a conceptually clear meaning.

Exploring nonlocal correlations in arbitrarily high-dimensional systems
New Journal of PhysicsThe utilization of higher-dimensional systems holds promise for unveiling novel phenomena and enhancing the efficacy of practical tasks, such as entanglement-based quantum cryptography. However, detecting quantum correlations within qudit systems poses a
