  • Eigenvalue measurement of topologically protected edge states in split-step quantum walks 
    Nitsche, Thomas; Geib, Tobias; Stahl, Christoph; Lorz, Lennart; Cedzich, Christopher; Barkhofen, Sonja; Werner, Reinhard F; Silberhorn, Christine (Bristol : Institute of Physics Publishing, 2019)
    We study topological phenomena of quantum walks by implementing a novel protocol that extends the range of accessible properties to the eigenvalues of the walk operator. To this end, we experimentally realise for the first ...
  • Translation invariant quantum walks with discrete symmetries 
    Stahl, Christoph (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Quantum walks are discrete-time evolutions of single particles on lattices that transfer the concept of classical random walks to quantum theory. Topological insulators are objects that promise symmetry-protected edge-states ...
