Bi-Contextuality: A Novel Non-Classical Phenomenon in Bipartite Quantum Systems
Gabriel Ruffolo, Nigel Benjamin Lee Junsheng, Kim Mu Young +4
We present and experimentally demonstrate a novel non-classical phenomenon, bi-contextuality, observed in quantum systems prepared by two independent sources. This discovery plays…
Trade-off relations between Bell nonlocality and local Kochen-Specker contextuality in generalized Bell scenarios
Lucas E. A. Porto, Gabriel Ruffolo, Rafael Rabelo +2
The relations between Bell nonlocality and Kochen-Specker contextuality have been subject of research from many different perspectives in the last decades. Recently, some interesti…
Quantum non-classicality in the simplest causal network
Pedro Lauand, Davide Poderini, Rafael Rabelo +1
Bell's theorem prompts us with a fundamental inquiry: what is the simplest scenario leading to the incompatibility between quantum correlations and the classical theory of causalit…
Estimating the volumes of correlations sets in causal networks
Giulio Camillo, Pedro Lauand, Davide Poderini +2
Causal networks beyond that in the paradigmatic Bell's theorem can lead to new kinds and applications of non-classical behavior. Their study, however, has been hindered by the fact…
