内容简介:When an n-partite physical system is measured by n observers, the joint probabilities of outcomes conditioned on the observables chosen by the n parties form a nonnegative tensor, called an n-partite correlation tensor (CT). Generally, CTs can be classified into signaling and nonsignaling ones according to the special relativity, as well as Bell local and Bell nonlocal ones from the point view of quantum mechanics.
In this talk, we will introduce some characterizations of nonsignaling and Bell locality of an n-partite CT, respectively,using singular valued decomposition (SVD) of matrices and a decomposition lemma about row-stochastic matrices,and give a close relationship between nonsignaling and Bell local CTs.
