Abstract

The understanding of entanglement measures and separability criteria are crucial problems in quantum information theory. In order to analyse the entanglement of pure tripartite GHZ states we used the Rest matrix. Relations between the maximal eigenvalues of the four possible Rest matrices and the total and bipartite tangles are found.
