We prove theorems analagous to classical theorems on mixing and ergodicity in terms of a quantum Koopman space $ L^2 (A_\hbar},τ_\hbar) $ obtained as the completion of the algebra of observables $ A_\hbar $ in the norm induced by the following inner product $(A,B) =τ_{\hbar}(A^{\dagger}B) $, where $τ_{\hbar}$ is a linear functional on the algebra analogous to the classical ``integral over phase space.'' We also derive explicit formulas connecting this formulation to the $θ$-torus decomposition of Bargmann space introduced in ref. \QCITE{cite}{}{KLMR}.27 pages, 2 figuresQuantum Physicstext
