ZX-calculus is a graphical language used in the field of quantum computing and quantum information theory. It provides a way to represent and manipulate quantum states and operations using graphical diagrams, which are composed of nodes and edges. The primary components of ZX-calculus are two kinds of vertices: green (Z) vertices and red (X) vertices, which correspond to different types of quantum operations.
