Multi-setting Bell inequality for qudits
Se-Wan Ji, Jinhyoung Lee, James Lim +2
We propose a generalized Bell inequality for two three-dimensional systems with three settings in each local measurement. It is shown that this inequality is maximally violated if…
Unconditional no-hidden-variables theorem
Koji Nagata
Recently, [{arXiv:0810.3134}] is accepted and published. We present ultimate version of no-hidden-variables theorem. We derive a proposition concerning the quantum theory under the…
Additional information decreases the estimated entanglement using the Jaynes principle
Koji Nagata
We study a particular example considered in {[Phys. Rev. A {\bf 59,} 1799 (1999)]}, concerning the statistical inference of quantum entanglement using the Jaynes principle. Assume…
Classification of local realistic theories
Koji Nagata
Recently, it has shown that an explicit local realistic model for the values of a correlation function, given in a two-setting Bell experiment (two-setting model), works only for t…
Necessary and sufficient condition for Greenberger-Horne-Zeilinger diagonal states to be full -partite entangled
Koji Nagata
Recently, [{arXiv:0810.3134}] is accepted and published. We show that any -qubit state which is diagonal in the Greenberger-Horne-Zeilinger basis is full -qubit entangled sta…
Multipartite positive-partial-transpose inequalities exponentially stronger than local reality inequalities
Koji Nagata
We show that positivity of {\it every} partial transpose of -partite quantum states implies new inequalities on Bell correlations which are stronger than standard Bell inequalit…
