| Research Abstract |
We studied classification and quantification of multipartite entanglemen by using a group theoretical method. For 3-qubit systems we found that our method can generate the known complete set of measures in a different form. For 4-qubit systems we confirmed that enough number of measures can be generated by our method. Many new measures are also found for systems with more than four qubits. We also made a computer program to generate measures for general multi-level systems.
