Quantum random walks using quantum accelerator modes.

Ma, Z. -Y. and Burnett, K. and d'Arcy, M. B. and Gardiner, S. A. (2006) 'Quantum random walks using quantum accelerator modes.', Physical review A., 73 (1). 013401.


We discuss the use of high-order quantum accelerator modes to achieve an atom optical realization of a biased quantum random walk. We first discuss how one can create coexistent quantum accelerator modes, and hence how momentum transfer that depends on the atoms' internal state can be achieved. When combined with microwave driving of the transition between the states, a different type of atomic beam splitter results. This permits the realization of a biased quantum random walk through quantum accelerator.
