Adlam's Frame: comment on "Wigner's Frame"
Andrea Di Biagio, Anne-Catherine de la Hamette
Recent no-go theorems based on extended Wigner's Friend scenarios (EWFS) reveal a deep tension between the universal validity of quantum theory and local friendliness (LF), the con…
Aumann's theorem beyond ontology: quantum, postquantum, and indefinite causal order
Carlo Cepollaro, Andrea Di Biagio
Agreement theorems are no-go results about rational disagreement: if two agents start from a common prior and their posterior beliefs are common knowledge, they cannot assign diffe…
On the emergence of preferred structures in quantum theory
Antoine Soulas, Guilherme Franzmann, Andrea Di Biagio
We assess the possibilities offered by Hilbert space fundamentalism, an attitude towards quantum physics according to which all physical structures (e.g. subsystems, locality, spac…
The simple reason why classical gravity can entangle
Andrea Di Biagio
Ever since gravity-induced entanglement (GIE) experiments have been proposed as a witness of the quantum nature of gravity, more and more theories of classical gravity coupled to q…
Relative Information, Relative Facts
Andrea Di Biagio, Carlo Rovelli
We offer a fresh perspective on the relational interpretation of quantum mechanics as a way of thinking about the world described by quantum theory based on quantifiable notions of…
Observables are glocal
Emil Broukal, Andrea Di Biagio, Eugenio Bianchi +1
We show that the problem of observables can be fully resolved for background independent theories defined on graphs, through the explicit construction of complete observables. The…
