Return probability of onedimensional discretetime quantum walks with finaltime dependence
Abstract
We analyze finaltime dependent discretetime quantum walks in one dimension. We compute asymptotics of the return probability of the quantum walk by a path counting approach. Moreover, we discuss a relation between the quantum walk and the corresponding finaltime dependent classical random walk.
