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 aiso discussed.
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.
