| Outline of Final Research Achievements |
This research investigated computation power of quantum computing, specifically measurement-based quantum computing, in terms of parameters developed in matroid minor theory by extending the theory itself. The power is characterized by the widths of matroids, and then a new approach using the BDD representing a quantum state is developed. The database of matroids of moderate sizes has been also maintained to use it for future computational analysis.
