Graphical Tests of Causality
Ãmin 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, Ãmin 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…
Flow of dynamical causal structures with an application to correlations
Ãmin Baumeler, Stefan Wolf
Causal models capture cause-effect relations both qualitatively - via the graphical causal structure - and quantitatively - via the model parameters. They offer a powerful framewor…
Quantum computation with indefinite causal structures
Mateus Araújo, Philippe Allard Guérin, Ãmin Baumeler
One way to study the physical plausibility of closed timelike curves (CTCs) is to examine their computational power. This has been done for Deutschian CTCs (D-CTCs) and post-select…
