Title: A Topological Approach to Quantum Contextuality

Abstract:
Non-locality and contextuality are paradoxical phenomena in quantum physics
that are of foundational and potentially great practical significance:
While non-locality is known to be fundamental to quantum communication,
the more general phenomenon of contextuality may provide a key resource for
quantum computation, as suggested by recent studies. This has motivated
several approaches to the high-level expression of non-locality and
contextuality that can be independent of the concrete formalism of quantum
mechanics.

Starting with a review of the paradoxical probabilistic behavior of
non-locality, this talk lays out some formalisms that express non-locality
and contextuality.  In particular, the topological approach makes it clear
that contextuality is isomorphic to various phenomena in other
disciplines.
We show two results, one on the relationship between probabilistic and
qualitative versions of contextuality, and the other on how to use a
topological idea to demonstrate (qualitative) contextuality.

This talk is based on several joint works with Samson Abramsky,
Rui Soares Barbosa, Ray Lal and Shane Mansfield.
