Quantum Walks on Regular Graphs and Eigenvalues

Combinatorics 2011-07-28 v2 Quantum Physics

Abstract

We study the transition matrix of a quantum walk on strongly regular graphs. It is proposed by Emms, Hancock, Severini and Wilson in 2006, that the spectrum of S+(U3)S^+(U^3), a matrix based on the amplitudes of walks in the quantum walk, distinguishes strongly regular graphs. We find the eigenvalues of S+(U)S^+(U) and S+(U2)S^+(U^2) for regular graphs.
