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…
Detecting nonlocality of noisy multipartite states with the CHSH inequality
Rafael Chaves, Antonio Acín, Leandro Aolita +1
The Clauser-Horne-Shimony-Holt inequality was originally proposed as a Bell inequality to detect nonlocality in bipartite systems. However, it can also be used to certify the nonlo…
Causal structures from entropic information: Geometry and novel scenarios
Rafael Chaves, Lukas Luft, David Gross
The fields of quantum non-locality in physics, and causal discovery in machine learning, both face the problem of deciding whether observed data is compatible with a presumed causa…
Nonlocality in sequential correlation scenarios
Rodrigo Gallego, Lars Erik Würflinger, Rafael Chaves +2
As first shown by Popescu [S. Popescu, Phys. Rev. Lett. 74, 2619 (1995)], some quantum states only reveal their nonlocality when subjected to a sequence of measurements while givin…
Entropic inequalities as a necessary and sufficient condition to noncontextuality and locality
Rafael Chaves
The assumption of local realism in a Bell locality scenario imposes non-trivial conditions on the Shannon entropies of the associated probability distributions, expressed by linear…
