From the abstract: > Quantification starts with sum and product rules that express combination and partition [...] measure theory formalizes addition, and probability theory formalizes inference in terms of proportions. Quantum theory rests on the same simple symmetries, but is formalized in two dimensions [...] in order to track an object through its binary interactions [...] The standard quantum formalism follows. There is no mystery or weirdness, just ordinary probabilistic inference.
