Family of Zeilinger-Horne-Greenberger "W" states lead to stronger nonclassicality than family of Greenberger-Horne-Zeilinger "GHZ" states
Aditi Sen De, Ujjwal Sen, Marcin Wiesniak +2
The N-qubit states of the W class, for N>10, lead to more robust (against noise admixture) violations of local realism, than the GHZ states. These violations are most pronounced fo…
Functional Bell inequalities can serve as a stronger entanglement witness
Aditi Sen De, Ujjwal Sen, Marek Zukowski
We consider a Bell inequality for a continuous range of settings of the apparatus at each site. This "functional" Bell inequality gives a better range of violation for generalized…
Local indistinguishability and LOCC monotones
Michal Horodecki, Aditi Sen De, Ujjwal Sen +1
We provide a method for checking indistinguishability of a set of multipartite orthogonal states by local operations and classical communication (LOCC). It bases on the principle o…
