We are organising a new workshop on quantum networks sponsored by the Foundational Questions Institute (FQXI) under the project "Quantum Bayesian networks: the physics of nonlocal events”.

The workshop will take place at the International Institute of Physics (http://www.iip.ufrn.br/) in Natal (Brazil) on 21 – 25 November 2016.

This will be the second in a series of three workshops, the first of which took place in Barcelona (http://qbnetworks.icfo.eu/).

Causality is a crucial concept for our understanding of nature. In relativity, the objective properties of a system are dictated by the causal relations between events in spacetime.
While quantum mechanical predictions comply with relativity, objective properties do not satisfy the same causal relations—the phenomenon known as non-locality.
Quantum mechanics is consistent with special relativity at an operational level but appears to violate it at an ontological level.
This reveals a deep subtlety in the way that quantum theory and relativity co-exist. Understanding this subtlety will be crucial to understanding how physical theories lead to a
notion of things happening through the language of causality. The aim of the workshop is to explore all these different concepts, bringing together researchers interested in
causality within quantum physics.

At the moment we have six invited speakers but more are to be confirmed:

Caslav Brukner (University of Vienna)
Nicolas Brunner (University of Geneva)
Costantino Budroni (University of Siegen)
Daniel Cavalcanti (ICFO)
Miguel Navascues (IQOQI-Vienna)
Rafael Rabelo (UFMG)

In addition, we anticipate accepting additional contributed talks and posters.

Registration and abstract submission are open.
