The relativity of indeterminacy
Flavio Del Santo, Nicolas Gisin
A long-standing tradition, largely present in both the physical and the philosophical literature, regards the advent of (special) relativity -- with its block-universe picture -- a…
Probing quantum coherence at a distance and Aharonov-Bohm non-locality
Sebastian Horvat, Philippe Allard Guerin, Luca Apadula +1
In a standard interferometry experiment, one measures the phase difference between two paths by recombining the two wave packets on a beam-splitter. However, it has been recently r…
An Unpublished Debate Brought to Light: Karl Popper's Enterprise against the Logic of Quantum Mechanics
Flavio Del Santo
Karl Popper published, in 1968, a paper that allegedly found a flaw in a very influential article of Birkhoff and von Neumann, which pioneered the field of "quantum logic". Neverth…
Comment on Healey's "Quantum Theory and the Limits of Objectivity"
Veronika Baumann, Flavio Del Santo, Caslav Brukner
In this comment we critically review an argument against the existence of objective physical outcomes, recently proposed by R. Healey [Foundations of Physics, 48(11), 1568-1589]. W…
Karl Popper's Forgotten Role in the Quantum Debate at the Edge between Philosophy and Physics in 1950s and 1960s
Flavio Del Santo
It is not very well known that the philosopher Karl Popper has been one of the foremost critics of the orthodox interpretation of quantum physics for about six decades. This paper…
