A Combinatorial Approach to Nonlocality and Contextuality
Antonio Acín, Tobias Fritz, Anthony Leverrier +1
So far, most of the literature on (quantum) contextuality and the Kochen-Specker theorem seems either to concern particular examples of contextuality, or be considered as quantum l…
Local orthogonality as a multipartite principle for quantum correlations
T. Fritz, A. B. Sainz, R. Augusiak +4
In recent years, the use of information principles to understand quantum correlations has been very successful. Unfortunately, all principles considered so far have a bipartite for…
Beyond Bell's Theorem: Correlation Scenarios
Tobias Fritz
Bell's Theorem witnesses that the predictions of quantum theory cannot be reproduced by theories of local hidden variables in which observers can choose their measurements independ…
On infinite-dimensional state spaces
Tobias Fritz
It is well-known that the canonical commutation relation can be realized only on an infinite-dimensional Hilbert space. While any finite set of experimental data can also…
Polyhedral duality in Bell scenarios with two binary observables
Tobias Fritz
For the Bell scenario with two parties and two binary observables per party, it is known that the no-signaling polytope is the polyhedral dual (polar) of the Bell polytope. Computa…
An entropic approach to local realism and noncontextuality
Rafael Chaves, Tobias Fritz
For any Bell locality scenario (or Kochen-Specker noncontextuality scenario), the joint Shannon entropies of local (or noncontextual) models define a convex cone for which the non-…
