In this paper we consider partially ordered algebraic structures arisi
ng in the semantics of formulas of a non commutative version of Girard
linear logic. The non commutative version we treat is the one recentl
y proposed by V. M. Abrusci. We introduce autonomous quantales and pro
ve a completion theorem from autonomous posets to autonomous quantales
and a representation theorem ''every autonomous quantale is isomorphi
c to a non commutative phase space quantale'', generalizing previous e
xisting results valid in the commutative case.
