Abstract

Non-locality is the phenomenon of observing strong correlations among the outcomes of local measurements of a multipartite physical system (particularly in quantum systems). No-signaling boxes are the abstract objects for studying non-locality, and wirings are local operations on the space of no-signaling boxes. This means that, no matter how non-local nature is, the set of physical non-local correlations must be closed under wirings. Then, one approach to identifying the non-locality of nature is to characterize closed sets of non-local correlations. Although non-trivial examples of wirings of no-signaling boxes are known, a systematic study of non-local correlations under wirings is a very hard problem. In this talk, after motivating the notion of no-signaling boxes, a measure of correlation will be introduced that is monotone under wirings. Using this measure, a continuum of sets of no-signaling boxes will be obtained that is closed under wirings.
