Causality in the quantum world: harnessing quantum effects in causal inference problems
17-20 September 2019. Anacapri, Italy






About the Workshop
Explaining the natural world in terms of cause and effect is the central pillar of science. Surprisingly, however, only recently a theory of causality was introduced, allowing to model causation in various fields of research. At least those governed by classical mechanics. To shake even more the foundations of causality, Bell’s theorem implies that our most basic notions of cause and effect are incompatible with quantum phenomena. Entangled quantum particles can be so strongly correlated that it seems like they behave as a single information unit, leading to the the apparent “spooky action at a distance” abhorred by Einstein in the phenomenon known as quantum non-locality. Both entanglement and non-locality are the core of the second quantum revolution as they enable the enhanced processing of quantum information in diverse applications. Yet, the understanding of entanglement and non-locality -and its interconnections to how we perceive space and time and manipulate information- has been mostly restricted to simple causal structures. To cope with that, a new research field has emerged to develop the basic framework to reason about causality in a quantum world. Concepts like causal networks, interventions and causal influence are finding more and more applications in quantum information at the same time that ideas and tools initially developed in a quantum setting are also being applied to purely classical phenomena.

It is in this interdisciplinary context that the workshop is inserted. It aims to bring together researchers working on causality, machine learning, artificial intelligence, quantum information and quantum foundations and foster collaborations and the emergence of new and exciting ideas.

The Workshop is organized within the Q-Causal Project Grant ID:61084 funded by the John Templeton Foundation.
