摘要: We study the localization of probability distribution in a discrete quantum random walk on an infinite chain. With phase defect introduced any position (QRW), we have found that QRW emerges. Different localized behaviors are presented when occupies different positions. Given coefficients stationary eigenstates relies coin operator, reveal positions, amplitude exhibits non-trivial dependence operator.
