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…

Discretization of continuous-time quantum walks via the staggered model with Hamiltonians
Gabriel Coutinho, Renato Portugal
We characterize a close connection between the continuous-time quantum-walk model and a discrete-time quantum-walk version, based on the staggered model with Hamiltonians in a clas…
