State transfer in strongly regular graphs with an edge perturbation
Chris Godsil, Krystal Guo, Mark Kempton +1
Quantum walks, an important tool in quantum computing, have been very successfully investigated using techniques in algebraic graph theory. We are motivated by the study of state t…
Average mixing matrix of trees
Chris Godsil, Krystal Guo, John Sinkovic
We investigate the rank of the average mixing matrix of trees, with all eigenvalues distinct. The rank of the average mixing matrix of a tree on vertices with distinct eige…
A New Perspective on the Average Mixing Matrix
Gabriel Coutinho, Chris Godsil, Krystal Guo +1
We consider the continuous-time quantum walk defined on the adjacency matrix of a graph. At each instant, the walk defines a mixing matrix which is doubly-stochastic. The average o…
