Optimal tests of genuine multipartite nonlocality
Mahasweta Pandit, Artur Barasinski, Istvan Marton +2
We propose an optimal numerical test for genuine multipartite nonlocality based on linear programming. In particular, we consider two non-equivalent models of local hidden variable…
Bounding the detection efficiency threshold in Bell tests using multiple copies of the maximally entangled two-qubit state carried by a single pair of particles
István Márton, Erika Bene, Tamás Vértesi
In this paper, we investigate the critical efficiency of detectors to observe Bell nonlocality using multiple copies of the maximally entangled two-qubit state carried by a single…
Activating hidden metrological usefulness
Géza Tóth, Tamás Vértesi, Paweł Horodecki +1
We consider bipartite entangled states that cannot outperform separable states in any linear interferometer. Then, we show that these states can still be more useful metrologically…
Strength and typicality of nonlocality in multisetting and multipartite Bell scenarios
Anna de Rosier, Jacek Gruca, Fernando Parisio +2
In this work we investigate the probability of violation of local realism under random measurements in parallel with the strength of these violations as described by resistance to…
-uniform mixed states
Waldemar Klobus, Adam Burchardt, Adrian Kolodziejski +4
We investigate the maximum purity that can be achieved by k-uniform mixed states of N parties. Such N-party states have the property that all their k-party reduced states are maxim…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
