Characterizing Signalling: Connections between Causal Inference and Space-time Geometry
Maarten Grothus, V. Vilasini
The paper studies how information‑theoretic notions of signalling relate to the geometric structure of space‑time, improving causal inference methods for unfaithful models and intr…

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)…

Routing Quantum Control of Causal Order
Maarten Grothus, Alastair A. Abbott, Augustin Vanrietvelde +1
In recent years, various frameworks have been proposed for the study of quantum processes with indefinite causal order. In particular, quantum circuits with quantum control of caus…
