qworld – Draw graphical calculus in monoidal categories and quantum theory

This is a LaTeX package specifically designed for typesetting graphical calculus in category theory and quantum computing. Built on top of TikZ, it offers an intuitive and extensible set of commands for constructing string diagrams involving monoidal categories, Frobenius structures, braidings, Hopf algebras, symmetries, dualities, pivotal structures, and dagger categories. The package provides precise control over diagram composition and enables readable diagrammatic reasoning.
