Staggered quantum walk on a line of diamonds

Cauê F. Teixeira da Silva, Daniel Posner, Renato Portugal

Resumo


The staggered model is a discrete-time quantum walk model, whose evolution operator is obtained from a set of graph tessellations. We use this model to analyze the standard deviation of the probability distribution on a line of diamonds. The results help to understand the dynamics of quantum walks and it can be used as tools for building quantum algorithms.
