 r networks have recently become important tools for understanding quantum 
 processes. In particular\, ZX-calculus has proven useful for quantum circu
 it compilation\, verification\, and simplification. This framework is extr
 emely flexible\, allowing proofs of quantum identities and exposing underl
 ying physics of quantum systems\, suggesting ZX-calculus as a useful desig
 n and reasoning language for condensed matter physics.  In this talk\, I w
 ill introduce ZX-calculus\, which is composed of graphical notation repres
 enting the quantum system (ZX-diagrams)\, and rewrite rules that allow def
 ormations of the diagrams. I will show how familiar objects (quantum circu
 its\, entangled states\, and measurements) can be represented and manipula
 ted diagrammatically\, and briefly connect this perspective to tensor-netw
 ork methods. Finally\, I will turn to recent applications in quantum many-
 body physics\, specifically by looking at how ZX-calculus can reveal entan
 glement transitions in systems under repeated measurements\, and how graph
 ical identities can be used to construct local parent Hamiltonians.
