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…

Bounding the persistency of the nonlocality of W states
Péter Diviánszky, Réka Trencsényi, Erika Bene +1
The nonlocal properties of the W states are investigated under particle loss. By removing all but two particles from an -qubit W state, the resulting two-qubit state is still en…
