Tailoring discrete quantum walk dynamics via extended initial conditions: Towards homogeneous probability distributions

arXiv:1004.0976 · doi:10.1088/1367-2630/12/12/123022

Abstract

We study the evolution of initially extended distributions in the coined quantum walk on the line by analyzing the dispersion relation of the process and its associated wave equations. This allows us, in particular, to devise an initially extended condition leading to a uniform probability distribution whose width increases linearly with time, with increasing homogeneity.
