We interpret Selinger and Valiron's quantum lambda calculus in the category of completely positive normal subunital maps between von Neumann algebras, and prove that the interpretation is adequate with respect to operational semantics.

Convex sets appear as state spaces of computation in an effectus, and form an effectus.
