Bimonoidal categories (also known as rig categories) are categories with two monoidal structures, one of which distributes over the other. We formally define sheet diagrams, a graphical calculus for bimonoidal categories that was informally introduced by Staton. Sheet diagrams are string diagrams drawn on a branching surface, which is itself an extruded string diagram. Our main result is a soundness and completeness theorem of the usual form for graphical calculi: we show that sheet diagrams… Expand

Differential 2-rigs
We explore the notion of a category with coproducts + and a monoidal structure ⊗ distributing over it, endowed with an endo-functor ∂ which is ‘linear and Leibniz’. Such ∂ can be legitimately calledExpand
Routed quantum circuits
TLDR
It is proved that this new framework allows for a consistent and intuitive diagrammatic representation in terms of circuit diagrams, applicable to both pure and mixed quantum theory, and exemplify its use in several situations, including the superposition of quantum channels and the causal decompositions of unitaries.

From fibered symmetric bimonoidal categories to symmetric spectra
In here we define the concept of fibered symmetric bimonoidal categories. These are roughly speaking fibered categories D->C whose fibers are symmetric monoidal categories parametrized by C and suchExpand

This article is intended as a reference guide to various notions of monoidal categories and their associated string diagrams. It is hoped that this will be useful not just to mathematicians, but alsoExpand
Bimonoidal Structure of Probability Monads
TLDR
A conceptual treatment of the notion of joints, marginals, and independence in the setting of categorical probability by endowing the usual probability monads with a monoidal and an opmonoidal structure, mutually compatible. Expand
STRICTIFICATION OF CATEGORIES WEAKLY ENRICHED IN SYMMETRIC MONOIDAL CATEGORIES
We show that categories weakly enriched over symmetric monoidal cate- gories can be strictied to categories enriched in permutative categories. This is a \many 0-cells" version of the stricticationExpand
Normalization for planar string diagrams and a quadratic equivalence algorithm
TLDR
It is shown that left- and right-handed exchanges each give strongly normalizing rewrite strategies for connected string diagrams, which gives a linear-time solution to the equivalence problem in the connected case, and a quadratic solution in the general case. Expand

TLDR
It is demonstrated how to represent quantum processes as proof-nets, and it is shown that the dynamic behaviour of a quantum process is captured by the cut-elimination procedure for the logic. Expand
The groupoid of finite sets is biinitial in the 2-category of rig categories
The groupoid of finite sets has a "canonical" structure of a symmetric 2-rig with the sum and product respectively given by the coproduct and product of sets. This 2-rigExpand
