Return probability of one-dimensional discrete-time quantum walks with final-time dependence
arXiv:1103.1180
Abstract
We analyze final-time dependent discrete-time 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 final-time dependent classical random walk.
