Spekkens's toy theory as a category of processes
Bob Coecke, Bill Edwards
We provide two mathematical descriptions of Spekkens's toy qubit theory, an inductively one in terms of a small set of generators, as well as an explicit closed form description. I…

Phase groups and the origin of non-locality for qubits
Bob Coecke, Bill Edwards, Robert W. Spekkens
We describe a general framework in which we can precisely compare the structures of quantum-like theories which may initially be formulated in quite different mathematical terms. W…

Toy quantum categories
Bob Coecke, Bill Edwards
We show that Rob Spekken's toy quantum theory arises as an instance of our categorical approach to quantum axiomatics, as a (proper) subcategory of the dagger compact category FRel…
