The Möbius Game: A Quantum-Inspired Test of General Relativity
Eleftherios-Ermis Tselentis, Ãmin Baumeler
We present a tight inequality to test the dynamical nature of spacetime. A general-relativistic violation of that inequality certifies change of curvature, in the same sense as a q…

Indefinite causal order in boxworld theories
Jessica Bavaresco, Ãmin Baumeler, Yelena Guryanova +1
An astonishing feature of higher-order quantum theory is that it can accommodate indefinite causal order. In the simplest bipartite setting, there exist signaling correlations for…
