Complex Hilbert spaces are the state spaces of quantum theory, and a powerful way to study them is to look at the category that they form. We will see how the structures that live on this category are intimately tied to the nature of the complex numbers, and by giving these categorical structures direct physical interpretations, we will obtain a new understanding of why the complex numbers should be important in a quantum theory of physics.
