Foliable Operational Structures for General Probabilistic Theories

Understand

In this chapter a general mathematical framework for probabilistic theories of operationally understood circuits is laid out.

• Circuits are comprised of operations and wires.
• An operation is one use of an apparatus and a wire is a diagrammatic device for showing how apertures on the apparatuses are placed next to each other.
• Mathematical objects are defined in terms of the circuit understood graphically.
