    • An example of such kind of basis is the one formed by the generalized Pauli operators. However, until Sec. IV we refrain from using a particular basis so our results remain general.

    • For example, for wco
    • For example, for w co < n / 2, it is trivial to prove that M co ≤ (w co + 1) (n e / w co) w co. In T. Worsch, Universität Karlsruhe, Fakultät für Informatik, Technical Report No. 31/94, 1994 [http://digbib.ubka.uni-karlsruhe.de/volltexte/181894], it is shown that M co ≤ (1 + ε) (√ n / 4 π) (n e / w co) w co, with ε O (1 / n). For a simple case where we find only up to two-body coefficients, then trivially M co = 1 + n + n (n - 1) / 2.
