定向图上的完美状态转移

Perfect State Transfer on Oriented Graphs

Chris Godsil, Sabrina Lato

摘要:

利用对称矩阵,如邻接矩阵或拉普拉斯矩阵,研究了无向图上的量子行走,并且已知许多关于完美状态转移的结果。我们将其中的一些结果推广到定向图。我们还研究了定向图所特有的多重状态转移现象,其中存在一组顶点,使得该组中的每一对顶点之间都发生完美状态转移。我们给出了多状态转移的一个特征,以及它发生的一个新的图的例子。

英文摘要:

Quantum walks on undirected graphs have been studied using symmetric matrices, such as the adjacency or Laplacian matrix, and many results about perfect state transfer are known. We extend some of those results to oriented graphs. We also study the phenomena, unique to oriented graphs, of multiple state transfer, where there is a set of vertices such that perfect state transfer occurs between every pair in that set. We give a characterization of multiple state transfer, and a new example of a graph where it occurs.
