Unified approach to geometric and positive-map-based non-linear entanglement identifiers
Marcin Markiewicz, Adrian Kolodziejski, Zbigniew Puchala +3
Detecting quantumness of correlations (especially entanglement) is a very hard task even in the simplest case i.e. two-partite quantum systems. Here we provide an analysis whether…

Bell measurement rules out supraquantum correlations
Łukasz Czekaj, Michał Horodecki, Tomasz Tylec
The so called bipartite non-signaling boxes are systems whose statistics is constrained solely by the principle of no instantaneous signaling between distant locations. Such system…
