摘要：

It is known that by Stochastic local operations and classical communication (SLOCC) a pure state of four qubits can be transformed to a state belonging to one of a set of nine families of states. Using the eigen vectors corresponding to negative eigenvalues of global partial transpose and the K-way partial transposes, we construct measures of genuine four-partite, tri-partite, and bi-partite entanglement for all the nine families of states.
