Finding structural anomalies in graphs by means of quantum walks
structural anomalies in graphs quantum walks
font style='font-size:12px;'>
2010/10/18
We explore the possibility of using quantum walks on graphs to find structural anomalies, such as extra edges or loops, on a graph. We focus our attention on star graphs, whose edges are like spokes c...
