ZX-calculus is a graphical language for quantum computing featured by strong complementarity. It can also be seen as a detailed version of Categorical Quantum Mechanics (CQM) in the sense that it could fill in any box (morphism) of CQM with green and red spiders. In this talk, I will first show some results on the theoretical side of ZX-calculus: completeness, algebraic axiomatisation, and generalisations to the cases of commutative rings and semirings, even a unified framework for all dimensional qudit ZX-calculus. Then I will give some results on applications of ZX-calculus: spider nest identities, T-count reduction, and fast probabilistic algorithm.
