Abstract

In this note, we discuss a general definition of quantum random walks on
graphs and illustrate with a simple graph the possibility of very different
behavior between a classical random walk and its quantum analogue. In this
graph, propagation between a particular pair of nodes is exponentially faster
in the quantum case.
