Skeleton structure inherent in discrete-time quantum walks
Tomoki Yamagami, Etsuo Segawa, Ken'ichiro Tanaka +4
In this paper, we claim that a common underlying structure--a skeleton structure--is present behind discrete-time quantum walks (QWs) on a one-dimensional lattice with a homogeneou…

Directivity of quantum walk via its random walk replica
Tomoki Yamagami, Etsuo Segawa, Nicolas Chauvet +3
Quantum walks (QWs) exhibit different properties compared with classical random walks (RWs), most notably by linear spreading and localization. In the meantime, random walks that r…
