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)…

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…

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…

Mapping indefinite causal order processes to composable quantum protocols in a spacetime

Matthias Salzger, V. Vilasini

Formalisms for higher order quantum processes provide a theoretical formalisation of quantum processes where the order of agents' operations need not be definite and acyclic, but m…

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…

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…

Impossibility of superluminal signalling in Minkowski space-time does not rule out causal loops

V. Vilasini, Roger Colbeck

Causality is fundamental to science, but it appears in several different forms. One is relativistic causality, which is tied to a space-time structure and forbids signalling outsid…

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…

A general framework for cyclic and fine-tuned causal models and their compatibility with space-time

V. Vilasini, Roger Colbeck

Causal modelling is a tool for generating causal explanations of observed correlations and has led to a deeper understanding of correlations in quantum networks. Existing framework…

On the insufficiency of entropic inequalities for detecting non-classicality in the Bell causal structure

V. Vilasini, Roger Colbeck

Classical and quantum physics impose different constraints on the joint probability distributions of observed variables in a causal structure. These differences mean that certain c…

Analysing causal structures using Tsallis entropies

V. Vilasini, Roger Colbeck

Understanding cause-effect relationships is a crucial part of the scientific process. As Bell's theorem shows, within a given causal structure, classical and quantum physics impose…
