The relative entropy of entanglement, the global robustness of entanglement and the geometric measure are equal for stabilizer quantum code words. The entanglement upper bounds can be get from the generator with Pauli measurement. Using an iterative algorithm can get the exact value of the entanglement.
The number of in equivalent classes of up to 8-qutrit graph states is 1002, with 239 decomposable graphs and 763 indecomposable graphs. Apparently, the former can be decomposed to several indecomposable parts. For qubit graph states, the upper and lower bounds of entanglement have been given. If the two bounds dont coincide, the entanglement can be calculated by iterative method. For qutrit graph...
