Cyclic Einstein-Podolsky-Rosen Steering

István Márton, Sándor Nagy, Erika Bene +1

Einstein-Podolsky-Rosen (EPR) steering is a form of quantum correlation that exhibits a fundamental asymmetry in the properties of quantum systems. Given two observers, Alice and B…

Experimentally friendly approach towards nonlocal correlations in multisetting N -partite Bell scenarios

Artur Barasiński, Antonín Černoch, Wiesław Laskowski +3

In this work, we study a recently proposed operational measure of nonlocality by Fonseca and Parisio~[Phys. Rev. A 92, 030101(R) (2015)] which describes the probability of violatio…

A class of genuinely high-dimensionally entangled states with a positive partial transpose

Károly F. Pál, Tamás Vértesi

Entangled states with a positive partial transpose (so-called PPT states) are central to many interesting problems in quantum theory. On one hand, they are considered to be weakly…

Self-testing non-projective quantum measurements in prepare-and-measure experiments

Armin Tavakoli, Massimiliano Smania, Tamás Vértesi +2

Self-testing represents the strongest form of certification of a quantum system. Here we investigate theoretically and experimentally the question of self-testing non-projective qu…

Survey on the Bell nonlocality of a pair of entangled qudits

Alejandro Fonseca, Anna de Rosier, Tamás Vértesi +2

The question of how Bell nonlocality behaves in bipartite systems of higher dimensions is addressed. By employing the probability of violation of local realism under random measure…

Qutrit witness from the Grothendieck constant of order four

Péter Diviánszky, Erika Bene, Tamás Vértesi

In this paper, we prove that , where denotes the Grothendieck constant of order . To this end, we use a branch-and-bound algorithm commonly used in the s…
