Pretty good state transfer on 1-sum of star graphs
Let A be the adjacency matrix of a graph G and suppose U(t) = exp(itA). We say that we have perfect state transfer in G from the vertex u to the vertex v at time t if there is a scalar γ of unit modulus such that U(t)eu = γ ev. It is known that perfect state transfer is rare. So C.Godsil gave a rela...
