Theories with no superluminal signaling have greater information-processing power than theories with no superluminal causation
V. Vilasini, Roger Colbeck
A central goal in the foundations of physics is to understand the structure of physical theories, such as quantum theory, from physical principles. This is often explored by consid…
Events and their Localisation are Relative to a Lab
V. Vilasini, Lin-Qing Chen, Liuhang Ye +1
The notions of events and their localisation fundamentally differ between quantum theory and general relativity, reconciling them becomes even more important and challenging in the…
The standard no-signalling constraints in Bell scenarios are neither sufficient nor necessary for preventing superluminal signalling with general interventions
V. Vilasini, Roger Colbeck
Non-classical correlations resulting from entangled quantum systems have sparked debates about the compatibility of quantum theory and relativity, and about the right way to think…
Fundamental limits for realising quantum processes in spacetime
V. Vilasini, Renato Renner
Understanding the interface between quantum and relativistic theories is crucial for fundamental and practical advances, especially given that key physical concepts such as causali…
Embedding cyclic information-theoretic structures in acyclic spacetimes: no-go results for indefinite causality
V. Vilasini, Renato Renner
The notions of causality adopted within the quantum information and spacetime physics communities are distinct. Although both notions play a role in physical experiments, their gen…
