Exploring the Local Orthogonality Principle
A. B. Sainz, T. Fritz, R. Augusiak +4
Nonlocality is arguably one of the most fundamental and counterintuitive aspects of quantum theory. Nonlocal correlations could, however, be even more nonlocal than quantum theory…
Quantum realization of arbitrary joint measurability structures
Ravi Kunjwal, Chris Heunen, Tobias Fritz
In many a traditional physics textbook, a quantum measurement is defined as a projective measurement represented by a Hermitian operator. In quantum information theory, however, th…
Quantum theory realises all joint measurability graphs
Chris Heunen, Tobias Fritz, Manuel L. Reyes
Joint measurability of sharp quantum observables is determined pairwise, and so can be captured in a graph. We prove the converse: any graph, whose vertices represent sharp observa…
Probabilistic models on contextuality scenarios
Tobias Fritz, Anthony Leverrier, Ana Belén Sainz
We introduce a framework to describe probabilistic models in Bell experiments, and more generally in contextuality scenarios. Such a scenario is a hypergraph whose vertices represe…
