A new type of quantum walks based on decomposing quantum states
Chusei Kiumi
In this paper, the 2-state decomposed-type quantum walk (DQW) on a line is introduced as an extension of the 2-state quantum walk (QW). The time evolution of the DQW is defined wit…

Eigenvalues of two-phase quantum walks with one defect in one dimension
Chusei Kiumi, Kei Saito
We study space-inhomogeneous quantum walks (QWs) on the integer lattice which we assign three different coin matrices to the positive part, the negative part, and the origin, respe…
