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…
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…
Analysing quantum systems with randomised measurements
Paweł Cieśliński, Satoya Imai, Jan Dziewior +6
Measurements with randomly chosen settings determine many important properties of quantum states without the need for a shared reference frame or calibration. They naturally emerge…
Self-testing of semisymmetric informationally complete measurements in a qubit prepare-and-measure scenario
Gábor Drótos, Károly F. Pál, Tamás Vértesi
Self-testing is a powerful method for certifying quantum systems. Initially proposed in the device-independent (DI) setting, self-testing has since been relaxed to the semi-device-…
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…
Activation of metrologically useful genuine multipartite entanglement
Róbert Trényi, Árpád Lukács, Paweł Horodecki +3
We consider quantum metrology with several copies of bipartite and multipartite quantum states. We characterize the metrological usefulness by determining how much the state outper…
