Periodicity of Grover walks on generalized Bethe trees
S. Kubota, E. Segawa, T. Taniguchi +1
This paper explains the perfect characterization of the generalized Bethe trees by analyzing the spectrum of its transition matrix.
On nonlinear scattering for quantum walks
Masaya Maeda, Hironobu Sasaki, Etsuo Segawa +2
We study large time behavior of quantum walks (QW) with self-dependent coin. In particular, we show scattering and derive the reproducing formula for inverse scattering in the weak…
How does Grover walk recognize the shape of crystal lattice?
Chul Ki Ko, Norio Konno, Etsuo Segawa +1
We consider the support of the limit distribution of the Grover walk on crystal lattices with the linear scaling. The orbit of the Grover walk is denoted by the parametric plot of…
Resonant-tunneling in discrete-time quantum walk
Kaname Matsue, Leo Matsuoka, Osamu Ogurisu +1
We show that discrete-time quantum walks on the line, , behave as "the quantum tunneling". In particular, quantum walkers can tunnel through a double-well with the tran…
Partition-based discrete-time quantum walks
Norio Konno, Renato Portugal, Iwao Sato +1
We introduce a family of discrete-time quantum walks, called two-partition model, based on two equivalence-class partitions of the computational basis, which establish the notion o…
Quantum Search on Simplicial Complexes
Kaname Matsue, Osamu Ogurisu, Etsuo Segawa
In this paper, we propose an extension of quantum searches on graphs driven by quantum walks to simplicial complexes. To this end, we newly define a quantum walk on simplicial comp…
