| Abstract: | The Fock construction used by Davies in his theory of quantum stochastic processes yields a semigroup of completely positive maps on the C1-algebra of the CCR. We show how such semigroups may be constructed using an arbitrary representation of the CCR and we investigate some of their properties. |
