Super-Activation of Quantum Steering
Marco Túlio Quintino, Marcus Huber, Nicolas Brunner
We consider Einstein-Podolsky-Rosen steering in the regime where the parties can perform collective measurements on many copies of a given shared entangled state. We derive a simpl…
Better local hidden variable models for two-qubit Werner states and an upper bound on the Grothendieck constant
Flavien Hirsch, Marco Túlio Quintino, Tamás Vértesi +2
We consider the problem of reproducing the correlations obtained by arbitrary local projective measurements on the two-qubit Werner state …
On the tightness of correlation inequalities with no quantum violation
Ravishankar Ramanathan, Marco Túlio Quintino, Ana Belén Sainz +2
We study the faces of the set of quantum correlations, i.e., the Bell and noncontextuality inequalities without any quantum violation. First, we investigate the question whether ev…
Entanglement without hidden nonlocality
Flavien Hirsch, Marco Túlio Quintino, Joseph Bowles +2
We consider Bell tests in which the distant observers can perform local filtering before testing a Bell inequality. Notably, in this setup, certain entangled states admitting a loc…
