本文研究了具有缺陷的多维分步量子行走的光谱,该缺陷在Fuda等人的先前论文中无法分析(Quantum Inf Process 18:203-226,2017; J Math Phys 59:082201,2018)。为此,我们已经开发了一种新的技术,使我们能够使用一个频谱映射定理的单缺陷模型。作为谱分析的一个应用,我们还导出了一维情形的时间平均极限测度。
This paper studies the spectrum of a multi-dimensional split-step quantum walk with a defect that cannot be analyzed in previous papers by Fuda et al. (Quantum Inf Process 18:203–226, 2017; J Math Phys 59:082201, 2018). To this end, we have developed a new technique which allow us to use a spectral mapping theorem for the one-defect model. We also derive the time-averaged limit measure for one-dimensional case as an application of the spectral analysis.
