The GRW flash theory: a relativistic quantum ontology of matter in space-time?
Get PDFJohn Bell proposed an ontology for the GRW modification of quantum mechanics in terms of flashes occurring at space-time points. The paper spells out the motivation for this ontology, enquires into the status of the wave-function in it, critically examines the claim of its being Lorentz-invariant and considers whether it is a parsimonious, but nevertheless physically adequate ontology

Naturalistic intuitionism for physics
Get PDFRecently, a novel intuitionistic reconstruction of the foundations of physics has been primarily developed by Nicolas Gisin and Flavio Del Santo drawing on naturalism. Our goal in this paper is to examine and develop the philosophical background of their naturalistic intuitionism for physics in contrast with Brouwer's defense of his intuitionistic mathematics. To be exact, we propose a systematic rearticulation of Brouwer's so-called two acts of intuitionism to serve as the self-contained philosophical framework justifying naturalistic intuitionism in physics. This revision is accompanied by an investigation of the distinctive naturalistic treatment of some central intuitionistic topics, including logic, language, time, ontology, meaning, and truth

Quantum non-locality Fundamentals and Applications in Quantum Information Science
No full textThis thesis is devoted to the study of quantum non-locality, in the framework of quantum information science. The research presented here includes both theoretical works on some fundamental concepts, such as the measurement process and quantum correlations, as well as some applications in modern quantum optics. As it is often the case in quantum information science, the joint study of fundamental notions and applications is very productive. While a better understanding of the fundamental concepts may lead to new applications, it happens also that applications shed new light on some fundamental notions..
Violation of the Finner inequality in the four-output triangle network
Get PDFNetwork nonlocality allows one to demonstrate nonclassicality in networks
with fixed joint measurements, that is without random measurement settings. The
simplest network in a loop, the triangle, with 4 outputs per party is
especially intriguing. The "elegant distribution" [N. Gisin, Entropy 21, 325
(2019)] still resists analytic proofs, despite its many symmetries. In
particular, this distribution is invariant under any output permutation. The
Finner inequality, which holds for all local and quantum distributions, has
been conjectured to be also valid for all no-signalling distributions with
independent sources (NSI distributions). Here we provide evidence that this
conjecture is false by constructing a 4-output network box that violate the
Finner inequality and prove that it satisfies all NSI inflations up to the
enneagon. As a first step toward the proof of the nonlocality of the elegant
distribution, we prove the nonlocality of the distributions that saturates the
Finner inequality by using geometrical arguments.Comment: 9 pages, 8 figures, Any comments are welcome ([email protected]
