A discontinuity of the energy of quantum walk in impurities
Kenta Higuchi, Takashi Komatsu, Norio Konno +2
We consider the discrete-time quantum walk whose local dynamics is denoted by at the perturbed region and free at the other positions. We obtain the station…

Feynman Integral in Quantum Walk, Barrier-top Scattering and Hadamard Walk
Kenta Higuchi
The aim of this article is to relate the discrete quantum walk on with the continuous Schrödinger operator on in the scattering problem. Each point of $\m…
