Information & Physics Beyond Causality

In physics and in computer science, causal structures are usually assumed to reflect a definite partial ordering of events: Causal relations are predetermined, and causal loops are excluded. In our project we relax this assumption in order to study the "non-causal" world from the point of view of both disciplines. This might lead to novel tools for information processing, and characterizations of physically realizable non-causal processes. Both tasks are interwoven and we expect that progress in one leads to progress in the other. Ultimately this study opens the doors to better understand quantum-physical effects, like non-local correlations.
