Typicality of Steering for Two-qubit States
Gerard Anglès Munné, Paweł Cieśliński, Tamás Vértesi +1
Phenomena that slip beyond the grasp of our classical intuition reveal uniquely quantum effects that deepen our understanding of the physical world and enable advances in informati…
Unmasking the Polygamous Nature of Quantum Nonlocality
Paweł Cieśliński, Lukas Knips, Mateusz Kowalczyk +4
Quantum mechanics imposes limits on the statistics of certain observables. Perhaps the most famous example is the uncertainty principle. Similar trade-offs also exist for the simul…
First-order optimality conditions for non-commutative optimization problems
Mateus Araújo, Igor Klep, Andrew J. P. Garner +2
We consider the problem of optimizing the state average of a polynomial of non-commuting variables, over all states and operators satisfying a number of polynomial constraints, and…
Symmetric multipartite Bell inequalities via Frank-Wolfe algorithms
Sébastien Designolle, Tamás Vértesi, Sebastian Pokutta
In multipartite Bell scenarios, we study the nonlocality robustness of the Greenberger-Horne-Zeilinger (GHZ) state. When each party performs planar measurements forming a regular p…
