A Discrete Transmission Line Model for Discrete-time Quantum Walks
Yusuke Fukushima, Tatsuaki Wada · Interdisciplinary Information Sciences · 2017
Based on the similarity between telegraph equation for transmission lines and Klein–Gordon equation, we have related a distributed element model in electrical engineering to a discrete-time quantum walk through Dirac equation. As a result, we have constructed a discrete transmission line model for a discrete-time quantum walk, and it enables us understanding the characteristics of quantum walks as those of the transmission line.
