  • Structural modifications of quasi-one-dimensional submonolayers by impurity doping 
    Godzik, G.; Block, T.; Pfnür, Herbert (College Park, MD : American Physical Society, 2004)
    In this study, carried out by analysis of intensities and spot profiles in low energy electron diffraction, we investigated the influence of electronegative oxygen atoms as dopants on the long range order, the thermal ...
  • Tensor-network approach for quantum metrology in many-body quantum systems 
    Chabuda, Krzysztof; Dziarmaga, Jacek; Osborne, Tobias J.; Demkowicz-Dobrzański, Rafał (London : Nature Publishing Group, 2020)
    Identification of the optimal quantum metrological protocols in realistic many particle quantum models is in general a challenge that cannot be efficiently addressed by the state-of-the-art numerical and analytical methods. ...
  • Training deep quantum neural networks 
    Beer, Kerstin; Bondarenko, Dmytro; Farrelly, Terry; Osborne, Tobias J.; Salzmann, Robert; Scheiermann, Daniel; Wolf, Ramona (Berlin : Nature Research, 2020)
    Neural networks enjoy widespread success in both research and industry and, with the advent of quantum technology, it is a crucial challenge to design quantum neural networks for fully quantum learning tasks. Here we propose ...
  • Typical local measurements in generalized probabilistic theories: emergence of quantum bipartite correlations 
    Kleinmann, M.; Osborne, Tobias J.; Scholz, Volkher B.; Werner, Albert H. (College Park, MD : American Physical Society, 2013)
    What singles out quantum mechanics as the fundamental theory of nature? Here we study local measurements in generalized probabilistic theories (GPTs) and investigate how observational limitations affect the production of ...
  • Uncertainty relations for angular momentum 
    Dammeier, Lars; Schwonnek, René; Werner, Reinhard F. (Bristol : Institute of Physics Publishing, 2015)
    In this work we study various notions of uncertainty for angular momentum in the spin-s representation of SU(2). We characterize the 'uncertainty regions' given by all vectors, whose components are specified by the variances ...
