Exploring maximally multipartite entanglement of even n qubits with N-tangle
Xin-Wei Zha, Jian-Xia Qi, Yun-Guang Zhang
A necessary condition of the maximally multipartite entangled states (MMES) is given via n-tangle. The condition shows that the n-tangle equal zero for the four-, and eight-qubit o…

The relation between tangle and local unitary invariants for pure three and four-qubit states
Xin-wei Zha, Yun-Guang Zhang, Jian-Xia Qi +1
A new form of local unitary (LU) transformation invariant is given for multi-qubit states . The general relation between tangle and the LU transformation invariant of pure three an…

Simple forms of SLOCC equivalent four-qubit \c{hi} state
Xin-Wei Zha, Jian-Xia Qi, Yun-Guang Zhang
Some simple structure of maximally four-qubit state is presented. Using stochastic local operations and classical communication (SLOCC) invariants, it is can be shown those simple…
