Tetrahedron genuine entanglement measure of four-qubit systems

Quantifying genuine entanglement is a key task in quantum information theory. We study the quantification of multipartite for four-qubit systems. Based on concurrence nine different classes states, with each class being closed under stochastic local operation and classical communication, we construct tetrahedron. Proper measure presented by using volume For non entangled pure classifies bi-separable entanglement. show that tetrahedron based not equivalent to four-partite concurrence. illustrate advantages detailed examples.
