    "abstract": "We generalize the quantum random walk protocol for a particle in a\none-dimensional chain, by using several types of biased quantum coins, arranged\nin aperiodic sequences, in a manner that leads to a rich variety of possible\nwave function evolutions. Quasiperiodic sequences, following the Fibonacci\nprescription, are of particular interest, leading to a sub-ballistic\nwavefunction spreading. In contrast, random sequences leads to diffusive\nspreading, similar to the classical random walk behaviour. We also describe how\nto experimentally implement these aperiodic sequences.",
