Graphical Tests of Causality
Ämin Baumeler, Eleftherios-Ermis Tselentis, Stefan Wolf
Bell inequalities limit the possible observations of non-communicating parties. Here, we present analogous inequalities for any number of communicating parties under the causal con…
No quantum advantage for violating fixed-order inequalities?
Veronika Baumann, Ämin Baumeler, Eleftherios-Ermis Tselentis
In standard quantum theory, the causal relations between operations are fixed. One can relax this notion by allowing for dynamical arrangements, where operations may influence the…
The Möbius Game: A Quantum-Inspired Test of General Relativity
Eleftherios-Ermis Tselentis, Ämin 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…
The Möbius game and other Bell tests for relativity
Eleftherios-Ermis Tselentis, Ämin Baumeler
We derive multiparty games that, if the winning chance exceeds a certain limit, prove the incompatibility of the parties' causal relations with any partial order. This, in turn, me…
Admissible Causal Structures and Correlations
Eleftherios-Ermis Tselentis, Ämin Baumeler
It is well-known that if one assumes quantum theory to hold locally, then processes with indefinite causal order and cyclic causal structures become feasible. Here, we study qualit…
Equivalence of Grandfather and Information Antinomy Under Intervention
Ämin Baumeler, Eleftherios Tselentis
Causal loops, e.g., in time travel, come with two main problems. Most prominently, the grandfather antinomy describes the potentiality to inconsistencies: a problem of logical natu…
