  • Constructing networks of quantum channels for state preparation 
    Bondarenko, Dmytro (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Entangled possibly mixed states are an essential resource for quantum computation, communication, metrology, and the simulation of many-body systems. It is important to develop and improve preparation protocols for such ...
  • Kohärente und dissipative Präparation von Quantenzuständen 
    Weimer, Hendrik (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    In den letzten Jahren wurden bei der Kontrolle von Quantenzuständen einzelner Atome, Moleküle und Spins in Festkörpern bahnbrechende Erfolge erzielt, und sogar quantenmechanische Verschränkung zwischen einzelnen Quantenobjekten ...
  • Time evolution and steady states of dissipative quantum many-body systems 
    Overbeck, Vincent Raphael (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    We investigate a dissipative Ising model that exhibits the Ising symmetry via a variational approach. In the non-equilibrium steady state phase diagram, we find a first order and a second order transition meeting at a ...
  • Topological phase transitions induced by varying topology and boundaries in the toric code 
    Jamadagni, Amit; Bhattacharyya, Arpan ([London] : IOP, 2021)
    One of the important characteristics of topological phases of matter is the topology of the underlying manifold on which they are defined. In this paper, we present the sensitivity of such phases of matter to the underlying ...
