Quantum walks driven by quantum coins with two multiple eigenvalues
Norio Konno, Iwao Sato, Etsuo Segawa +1
We consider a spectral analysis on the quantum walks on graph with the local coin operators and the flip flop shift. The quantum coin operators have co…
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…
Quaternionic quantum walks of Szegedy type and zeta functions of graphs
Norio Konno, Kaname Matsue, Hideo Mitsuhashi +1
We define a quaternionic extension of the Szegedy walk on a graph and study its right spectral properties. The condition for the transition matrix of the quaternionic Szegedy walk…
The discrete-time quaternionic quantum walk on a graph
Norio Konno, Hideo Mitsuhashi, Iwao Sato
Recently, the quaternionic quantum walk was formulated by the first author as a generalization of discrete-time quantum walks. We treat the right eigenvalue problem of quaternionic…
A remark on zeta functions of finite graphs via quantum walks
Yu. Higuchi, N. Konno, I. Sato +1
From the viewpoint of quantum walks, the Ihara zeta function of a finite graph can be said to be closely related to its evolution matrix. In this note we introduce another kind of…
Quantum graph walks I: mapping to quantum walks
Yusuke Higuchi, Norio Konno, Iwao Sato +1
We clarify that coined quantum walk is determined by only the choice of local quantum coins. To do so, we characterize coined quantum walks on graph by disjoint Euler circles with…
