Quantum Foundations Beyond Bell's Theorem: A Topical Review
Flavio Del Santo, Nicolas Gisin
We review a series of recent no-go theorems that extend the methodological and conceptual framework introduced by Bell's theorem to more sophisticated operational scenarios involvi…
Schrödinger's unpublished hidden-variable model in the 1944-45 debate over the "Collapse of Determinism"
Flavio Del Santo
In the mid-1940s, the question of whether quantum mechanics could be supplemented by deterministic hidden variables resurfaced in a debate in ^textit{Nature}. I show that Erwin Sch…
Reply to the Comment on "The Axiom of Choice and the No-Signalling Principle"
Ämin Baumeler, Borivoje Dakić, Flavio Del Santo +1
We clarify the meaning of a probabilistic no-signalling strategy in Ref [Proc. R. Soc. A 481, 20240601]. For every fixed input, the deterministic strategy constructed using the Axi…
Was Schrödinger ever a determinist?
Flavio Del Santo, Nicolas Gisin
Erwin Schrödinger is often portrayed as a reactionary who resisted the indeterminism introduced by quantum mechanics, but on closer inspection his views on determinism prove to be…
Classical and quantum mechanics across representations: an operational reading of the Wigner Weyl correspondence
Samuel Schlegel, Borivoje Dakić, Flavio Del Santo
The physical content of a theory is not intrinsically tied to any single mathematical formalism. Both classical and quantum mechanics admit equivalent representations, notably in p…
Superluminal Transformations and Indeterminism
Amrapali Sen, Flavio Del Santo
Quantum theory is widely regarded as fundamentally indeterministic, yet classical frameworks can also exhibit indeterminism once infinite information is abandoned. At the same time…
Quantum coherence in networks
Fatemeh Bibak, Flavio Del Santo, Borivoje Dakić
From a quantum information perspective, verifying quantum coherence in a quantum experiment typically requires adjusting measurement settings or changing inputs. A paradigmatic exa…
Wigner's friend scenarios: on what to condition and how to verify the predictions
Flavio Del Santo, Gonzalo Manzano, Caslav Brukner
Wigner's friend experiment and its modern extensions display the ambiguity of the quantum mechanical description regarding the assignment of quantum states. While the friend applie…
Creative and geometric times in physics, mathematics, logic, and philosophy
Flavio Del Santo, Nicolas Gisin
We distinguish two different concepts of time that play a role in physics: \textit{geometric time} and \textit{creative time}. The former is the time of deterministic physics and m…
On playing gods: The fallacy of the many-worlds interpretation
Luis C. Barbado, Flavio Del Santo
We present a methodological argument to refute the so-called many-worlds interpretation (MWI) of quantum theory. Several known criticisms in the literature have already pointed out…
Towards a measurement theory in QFT: "Impossible" quantum measurements are possible but not ideal
Nicolas Gisin, Flavio Del Santo
Naive attempts to put together relativity and quantum measurements lead to signaling between space-like separated regions. In QFT, these are known as impossible measurements. We sh…
Between understanding and control: Science as a cultural product
Flavio Del Santo
Since the early days of humankind, people have been asking questions about Nature of two kinds: why did that happen? And how can that be used? In a broad sense, science was born th…
Against the "nightmare of a mechanically determined universe": Why Bohm was never a Bohmian
Flavio Del Santo, Gerd Christian Krizek
David Bohm has put forward the first deterministic interpretation of quantum physics, and for this he seems to be regarded as a champion of determinism by physicists (both his cont…
Potentiality realism: A realistic and indeterministic physics based on propensities
Flavio Del Santo, Nicolas Gisin
We propose an interpretation of physics named potentiality realism. This view, which can be applied to classical as well as to quantum physics, regards potentialities (i.e. intrins…
The Axiom of Choice and the No-Signaling Principle
Ämin Baumeler, Borivoje Dakić, Flavio Del Santo
We show that the axiom of choice, a basic yet controversial postulate of set theory, leads to revise the standard understanding of one of the pillars of our best physical theories,…
The open past in an indeterministic physics
Flavio Del Santo, Nicolas Gisin
Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of wh…
Comment on "Quantum principle of relativity"
Flavio Del Santo, Sebastian Horvat
A. Dragan and A. Ekert [New Journal of Physics, 22(3), p.033038.] have recently claimed that fundamental properties of quantum physics (e.g. fundamental indeterminism and the princ…
"Philosophysics" at the University of Vienna: The (pre-)history of foundations of quantum physics in the Viennese cultural context
Flavio Del Santo, Emanuel Schwarzhans
Vienna today is one of the capitals for the research on foundations of quantum physics. In this paper we reconstruct the main historical steps of the development of modern physics…
Beyond method: The diatribe between Feyerabend and Popper over the foundations of quantum mechanics
Flavio Del Santo
Karl Popper and Paul Feyerabend have been among the most influential philosophers of science of the twentieth century. Extensive studies have been dedicated to the development of t…
The Foundations of Quantum Mechanics in Post-War Italy's Cultural Context
Flavio Del Santo
After World War II, a hyper-pragmatic paradigm was established in physics in most of the western countries, within which foundations of quantum mechanics were vastly dismissed as p…
A no-go theorem for the persistent reality of Wigner's friend's perception
Philippe Allard Guérin, Veronika Baumann, Flavio Del Santo +1
The notorious Wigner's friend thought experiment (and modifications thereof) has in recent years received renewed interest especially due to new arguments that force us to question…
Indeterminism, causality and information: Has physics ever been deterministic?
Flavio Del Santo
A tradition handed down among physicists maintains that classical physics is a perfectly deterministic theory capable of predicting the future with absolute certainty, independentl…
Generalized probability rules from a timeless formulation of Wigner's friend scenarios
Veronika Baumann, Flavio Del Santo, Alexander R. H. Smith +3
The quantum measurement problem can be regarded as the tension between the two alternative dynamics prescribed by quantum mechanics: the unitary evolution of the wave function and…
Two-way communication with a single quantum particle
Flavio Del Santo, Borivoje Dakić
In this letter we show that communication when restricted to a single information carrier (i.e. single particle) and finite speed of propagation is fundamentally limited for classi…
