摘要
To obtain a classification of correlations of tripartite mixed states, various correlated states are introduced by using measurement-induced disturbance, including CCC, QC, GQC, CCX, CXC, XCC, CXX, XCX and XXC-states. Standard forms of them are established and equivalent characterizations of them are obtained in terms of normality and commutativity of the associated component operators.
