“Quantum Bayesian networks: the physics of nonlocal events”

Here is the announcement of the third event of the series: “Quantum Bayesian networks: the physics of nonlocal events”. The last one in Natal was great!

Dear colleagues,

We are organising a workshop on quantum networks sponsored by the Foundational Questions Institute (FQXI) under the project “Quantum Bayesian networks: the physics of nonlocal events”. This will the last in a series of three workshops, the first of which took place in Barcelona (http://qbnetworks.icfo.eu/), and the second in Natal, Brazil (http://iip.ufrn.br/eventsdetail.php?inf===QTUVkM).

The workshop will take place at the Department of Computer Science (http://www.cs.ox.ac.uk) at the University of Oxford, UK on 1st-4th August 2017.

The workshop webpage is: http://www.cs.ox.ac.uk/qnetworks2017

We have the following invited speakers:

Fabio Costa (University of Queensland)
Robin Evans (University of Oxford)
Lucien Hardy (Perimeter Institute)
Matt Leifer (Chapman University)
Ognyan Oreshkov (University of Oxford)
Jacques Pienaar (IIP Natal, Brazil)
Stefano Pironio (Université Libre de Bruxelles)
Ana Belén Sainz (Perimeter Institute)
Philip Walther (University of Vienna)
Stephanie Wehner (Delft University of Technology)

In addition, we anticipate accepting additional contributed talks and posters (deadline 28th May 2017). Abstract submission is open at https://easychair.org/conferences/?conf=qnetworks2017.

Registration will be opening shortly so please check back in the coming days to register. We are also offering limited financial support to students and postdoctoral researchers. Please consult the workshop website for details.

Background: 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.

We look forward to seeing you in Oxford!
