Generalized eigenfunctions for quantum walks via path counting approach
Takashi Komatsu, Norio Konno, Hisashi Morioka +1
We consider the time-independent scattering theory for time evolution operators of one-dimensional two-state quantum walks. The scattering matrix associated with the position-depen…
Quantum search of matching on signed graphs
Etsuo Segawa, Yusuke Yoshie
We construct a quantum searching model of a signed edge driven by a quantum walk. The time evolution operator of this quantum walk provides a weighted adjacency matrix induced by t…
A crossover between open quantum random walks to quantum walks
Norio Konno, Kaname Matsue, Etsuo Segawa
We propose an intermediate walk continuously connecting an open quantum random walk and a quantum walk with parameters controlling a decoherence effect; if ,…
Electric circuit induced by quantum walk
Yusuke Higuchi, Mohamed Sabri, Etsuo Segawa
We consider the Szegedy walk on graphs adding infinite length tails to a finite internal graph. We assume that on these tails, the dynamics is given by the free quantum walk. We se…
