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…

Beating one bit of communication with and without quantum pseudo-telepathy

István Márton, Erika Bene, Péter Diviánszky +1

According to Bell's theorem, certain entangled states cannot be simulated classically using local hidden variables (LHV). But if can we augment LHV by classical communication, how…

Self-testing in prepare-and-measure scenarios and a robust version of Wigner's theorem

Miguel Navascues, Károly F. Pál, Tamás Vértesi +1

We consider communication scenarios where one party sends quantum states of known dimensionality , prepared with an untrusted apparatus, to another, distant party, who probes th…
