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…
Gravity-induced entanglement is not a theory-independent witness of nonclassicality of the gravitational field
Andrea Di Biagio
Gravity-induced entanglement (GIE) experiments have been proposed as a theory-independent test of the quantum nature of gravity, on the strength of several no-go theorems concludin…
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…
A truly relativistic gravity mediated entanglement protocol using superpositions of rotational energies
Gerard Higgins, Andrea Di Biagio, Marios Christodoulou
Experimental proposals for testing quantum gravity-induced entanglement of masses (QGEM) typically involve two interacting masses which are each in a spatial superposition state. H…
On the Time Orientation of Probabilistic Theories
Andrea Di Biagio, Carlo Rovelli
An influential theorem by Satosi Watanabe convinced many that there can be no physical probabilistic theory with both non-trivial forward and backward transition probabilities. We…
Gravity Mediated Entanglement between Oscillators as Quantum Superposition of Geometries
Ofek Bengyat, Andrea Di Biagio, Markus Aspelmeyer +1
Protocols for observing gravity induced entanglement typically comprise the interaction of two particles prepared either in a superposition of two discrete paths, or in a continuou…
On the consistency of relative facts
Eric G. Cavalcanti, Andrea Di Biagio, Carlo Rovelli
Lawrence et al. have presented an argument purporting to show that "relative facts do not exist" and, consequently, "Relational Quantum Mechanics is incompatible with quantum mecha…
Circuit locality from relativistic locality in scalar field mediated entanglement
Andrea Di Biagio, Richard Howl, Časlav Brukner +2
Locality is a central notion in modern physics, but different disciplines understand it in different ways. Quantum field theory focuses on relativistic locality, based on spacetime…
Gravity entanglement, quantum reference systems, degrees of freedom
Marios Christodoulou, Andrea Di Biagio, Richard Howl +1
We discuss the physical interpretation of the gravity mediated entanglement effect. We show how to read it in terms of quantum reference systems. We pinpoint the single gravitation…
Photonic Implementation of Quantum Gravity Simulator
Emanuele Polino, Beatrice Polacchi, Davide Poderini +6
Detecting gravity mediated entanglement can provide evidence that the gravitational field obeys quantum mechanics. We report the result of a simulation of the phenomenon using a ph…
Relational Quantum Mechanics is about Facts, not States: A reply to Pienaar and Brukner
Andrea Di Biagio, Carlo Rovelli
In recent works, Časlav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail a…
The arrow of time in operational formulations of quantum theory
Andrea Di Biagio, Pietro Donà, Carlo Rovelli
The operational formulations of quantum theory are drastically time oriented. However, to the best of our knowledge, microscopic physics is time-symmetric. We address this tension…
An experiment to test the discreteness of time
Marios Christodoulou, Andrea Di Biagio, Pierre Martin-Dussaud
Time at the Planck scale () is an unexplored physical regime. It is widely believed that probing Planck time will remain for long an impossible task. Yet…
Stable Facts, Relative Facts
Andrea Di Biagio, Carlo Rovelli
Facts happen at every interaction, but they are not absolute: they are relative to the systems involved in the interaction. Stable facts are those whose relativity can effectively…
