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…
Closing the detection loophole in multipartite Bell experiments with a limited number of efficient detectors
Kamil Kostrzewa, Wieslaw Laskowski, Tamas Vertesi
The problem of closing the detection loophole in Bell tests is investigated in the presence of a limited number of efficient detectors using emblematic multipartite quantum states.…
EPR Steering inequalities with Communication Assistance
Sándor Nagy, Tamás Vértesi
In this paper, we investigate the communication cost of reproducing Einstein-Podolsky-Rosen (EPR) steering correlations arising from bipartite quantum systems. We characterize the…
