Title: Of Quantum Walk, Particles and Quotient Graphs.
Abstract: In a quantum walk on a finite graph, perfect state transfer occurs between two vertices if the unit vectors at these vertices are mapped to each other. This phenomenon is known to be relevant for quantum transport in spin chains. There is a strong interplay between quantum walk with many particles, graph products, and quotients modulo equitable partitions. A goal of this talk is to describe how to view these connections through the lens of algebraic graph theory and to show how this is useful for exploring perfect state transfer.
