Certification of qubits in the prepare-and-measure scenario with large input alphabet and connections with the Grothendieck constant
Péter Diviánszky, István Márton, Erika Bene +1
We address the problem of testing the quantumness of two-dimensional systems in the prepare-and-measure (PM) scenario, using a large number of preparations and a large number of me…
Iterative optimization in quantum metrology and entanglement theory using semidefinite programming
Árpád Lukács, Róbert Trényi, Tamás Vértesi +1
We discuss efficient methods to optimize the metrological performance over local Hamiltonians in a bipartite quantum system. For a given quantum state, our methods find the best lo…
Platonic Bell inequalities for all dimensions
Károly F. Pál, Tamás Vértesi
In this paper we study the Platonic Bell inequalities for all possible dimensions. There are five Platonic solids in three dimensions, but there are also solids with Platonic prope…
Naturally restricted subsets of nonsignaling correlations: typicality and convergence
Pei-Sheng Lin, Tamás Vértesi, Yeong-Cherng Liang
It is well-known that in a Bell experiment, the observed correlation between measurement outcomes -- as predicted by quantum theory -- can be stronger than that allowed by local ca…
