Qufinite ZX-calculus: a unified framework of qudit ZX-calculi

This paper by CQC Scientist Quanlong Wang provides a basis for a proof of completeness of qudit ZX-calcluli and their unified formalism qufinite ZX-calculus, which intuitively means quantum computing for qudits, or hybrid finite-dimensional quantum systems, can be done purely diagrammatically. Furthermore, this paper establishes a framework for a reconstruction of finite quantum theory which focuses on compositionality without resorting to any probability theory or sum structures.
