Impossibility of superluminal signalling rules out causal loops in conical spacetimes
Maarten Grothus, V. Vilasini
In PRL 129, 110401 it was shown that it is theoretically possible to have operationally detectable causal loops without violating the principle of no superluminal signalling (NSS)…
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…
