WebNov 25, 2024 · These nullifiers can easily be seen to correspond to the canonical graph of a GHZ state figure 4, right . The difference in connectivity, or valence, of a QC cluster and a GHZ graph is significant: the cluster graph possesses a local structure, i.e. one can define a set of nearest-neighbors, or neighborhood, for each qubit. WebFeb 2, 2012 · 2.1 Graph and Graph State. A graph is a collection of vertices and description of which vertices are connected by an edge. A graph is a pair G=(V,E) of a finite set V and a set E⊂V×V, where the elements of V and E are called vertices and edges, respectively.In this paper, the vertices of the graphs take the role of tow-level quantum …

WebJan 17, 2013 · One such example is the GHZ state pictured in figure 2. This graph state corresponds to a star graph which can be transformed to a complete graph using local complementation. So the graph states corresponding to a star graph and a complete graph are LC-equivalent and therefore have the same entanglement of 1.
