Observation of stronger-than-binary correlations with entangled photonic qutrits
Xiao-Min Hu, Bi-Heng Liu, Yu Guo +7
We present the first experimental confirmation of the quantum-mechanical prediction of stronger-than-binary correlations. These are correlations that cannot be explained under the…
Quantum states with a positive partial transpose are useful for metrology
Géza Tóth, Tamás Vértesi
We show that multipartite quantum states that have a positive partial transpose with respect to all bipartitions of the particles can outperform separable states in linear interfer…
Family of Bell inequalities violated by higher-dimensional bound entangled states
Karoly F Pal, Tamas Vertesi
We construct ()-dimensional bound entangled states, which violate, for any , a bipartite Bell inequality introduced in this paper. We conjecture that the proposed c…
Multipartite nonlocality and random measurements
Anna de Rosier, Jacek Gruca, Fernando Parisio +2
We present an exhaustive numerical analysis of violations of local realism by families of multipartite quantum states. As an indicator of nonclassicality we employ the probability…
