The Computational Power of Quantum Walk
Andrew MacGregor Childs - University of Waterloo, Ontario, Canada
Abstract
Quantum computers have the potential to solve certain problems dramatically faster than classical computers. One of the main quantum algorithmic tools is the notion of quantum walk, a quantum mechanical analog of random walk. I will describe quantum algorithms based on this idea, including an optimal algorithm for evaluating Boolean formulas and the best known algorithm for simulating quantum systems. I will also show how quantum walk can be viewed as a universal model of quantum computation.
