Axiomatic description of mixed states from Selinger`s CPM
... In [11] Selinger proposed an intriguing construction of mixed states and completely positive maps given any †-compact category representing a semantics for pure state quantum informatics in the sense of Abramsky and the author [1,2]. Conceptually speaking, in Selinger’s construction an ancillary sys ...
