Nonlocality in many-body quantum systems detected with two-body correlators
J. Tura, R. Augusiak, A. B. Sainz +4
Contemporary understanding of correlations in quantum many-body systems and in quantum phase transitions is based to a large extent on the recent intensive studies of entanglement…
Postquantum steering
Ana Belen Sainz, Nicolas Brunner, Daniel Cavalcanti +2
The discovery of postquantum nonlocality, i.e., the existence of nonlocal correlations that are stronger than any quantum correlations but nevertheless consistent with the no-signa…
A new property of the Lovász number and duality relations between graph parameters
Antonio Acín, Runyao Duan, David E. Roberson +2
We show that for any graph , by considering "activation" through the strong product with another graph , the relation between the independence number…
Entanglement and Nonlocality in Many-Body Systems: a primer
J. Tura, A. B. Sainz, T. Grass +3
Current understanding of correlations and quantum phase transitions in many-body systems has significantly improved thanks to the recent intensive studies of their entanglement pro…
Macroscopic non-contextuality as a principle for Almost Quantum Correlations
Joe Henson, Ana Belén Sainz
Quantum mechanics allows only certain sets of experimental results (or "probabilistic models") for Bell-type quantum non-locality experiments. A derivation of this set from simple…
