Abstract

A critical problem in quantum information theory involves the transfer of a quantum state through a network of interacting qubits.  In recent years, a large body of literature has been produced that has looked at this problem using tools from algebraic and spectral graph theory.  I will discuss one such tool, the isospectral reduction, that has recently been shown to be closely tied to the quantum state transfer question.
