A **graph state** is a special type of quantum state associated with a certain graph in quantum information theory. Graph states are fundamental in the context of quantum computing and quantum information processing, particularly in the study of quantum entanglement. Here's a more detailed explanation: 1. **Graph Representation**: A graph \( G \) is defined by a set of vertices (or nodes) \( V \) and edges \( E \) that connect pairs of vertices.
