Revealing Hidden Genuine Tripartite Nonlocality
Nonlocal correlations arising from measurements on tripartite entangled
states can be classified into two groups, one genuinely way nonlocal and
other local with respect to some bipartition. Still, whether a genuinely
tripartite entangled quantum state can exhibit genuine way nonlocality,
remains a challenging problem so far as measurement context is concerned. Here
we introduce a novel approach in this regard. We consider three tripartite
quantum states none of which is genuinely way nonlocal in a specific Bell
scenario (three parties, two measurements per party, two outcomes per
measurement), but they can exhibit genuine way nonlocality when the initial
states are subjected to stochastic local operations and classical communication
(SLOCC). So, genuine way nonlocality is a resource, which can be revealed
by using a sequence of measurements.Comment: 10 pages, 2 figures, revtex, comments welcom
