    "abstract": "We study the dynamics of a generalization of quantum coin walk on the line\nwhich is a natural model for a diffusion modified by quantum or interference\neffects. In particular, our results provide surprisingly simple explanations to\nphenomena observed by Bouwmeester et al. (Phys. Rev. A, 61, 13410 (1999)) in\ntheir optical Galton board experiment, and a description of a stroboscopic\nquantum walks given by Buershaper and Burnett (quant-ph/0406039) through\nnumerical simulations. We also provide heuristic explanations for the behavior\nof our model which show, in particular, that its dynamics can be viewed as a\ndiscrete version of Bloch oscillations.",
