Three-Tangle for High-Rank Mixed States
Shujuan He, Xiaohong Wang, Shao-Ming Fei, Hongxiang Sun, Qiaoyan Wen · Communications in Theoretical Physics · 2011
A family of rank-n (n = 5,6,7,8) three-qubit mixed states are constructed. The explicit expressions for the three-tangle and optimal decompositions for all these states are given. The CKW relations for these states are also discussed.
