POVMs and Naimark's Theorem Without Sums
duce an abstract notion of POVM within the categorical quantum mechanical semantics in terms act categories. Our definition is justified by two facts: i. we provide a purely graphical abstract counterpart to Naimark's theorem, which establishes a bijective correspondence between POVMs and abstract projective measurements on an extended system; ii. in the category of Hilbert spaces and linear maps our definition coincides with the usual one.
