A note on diagonal gates in SZX-calculus

Quantum Physics 2020-12-18 v1

Abstract

This note describes how the the scalable ZXH calculus can be used to represent in a compact way the quantum gates that are diagonal in the computational basis. This includes controlled and multi-controlled Z gates, their generalizations, respectively graph and hypergraph operators, and also phase gadgets.
