  • Decoherence models for discrete-time quantum walks and their application to neutral atom experiments 
    Alberti, Andrea; Alt, Wolfgang; Werner, Reinhard F.; Meschede, Dieter (Bristol : IOP Publishing Ltd., 2014-12-19)
    We discuss decoherence in discrete-time quantum walks in terms of a phenomenological model that distinguishes spin and spatial decoherence. We identify the dominating mechanisms that affect quantum-walk experiments realized ...
  • Molecular binding in interacting quantum walks 
    Ahlbrecht, Andre; Alberti, Andrea; Meschede, Dieter; Scholz, Volkher B.; Werner, Albert H.; Werner, Reinhard F. (Bristol : IOP Publishing Ltd., 2012)
    We show that the presence of an interaction in the quantum walk of two atoms leads to the formation of a stable compound, a molecular state. The wave function of the molecule decays exponentially in the relative position ...
