摘要

This work is intended as an attempt to motivate a novel model of disordering discrete-time quantum walk in a one-dimensional lattice of integers. We construct such a model over max-plus algebra and give the notion of coin operator of the disordered discrete-time quantum walk in a one-dimensional lattice \(\mathbb {Z}\) Z to derive a very complicated decision matrix. Furthermore, we investigate the properties of the decision matrix for each state and prove some results for the disordered quantum walk over max-plus algebra that are similar to the conserved quantity of the conventional disordered quantum walk.
