Abstract
Finite quantum systems are considered and dual quantities are defined with a finite Fourier transform. Ladder operators that translate the e igenstates of these quantities are shown to form a finite Weyl group. Dual measurements are introduced and shown to obey certain entropic in equalities. A factorization of these systems into subsystems with the use of number-theoretic results is also presented.
