  • Efficient reliability analysis of complex systems in consideration of imprecision 
    Salomon, Julian; Winnewisser, Niklas; Wei, Pengfei; Broggi, Matteo; Beer, Michael (London [u.a.] : Elsevier Science, 2021)
    In this work, the reliability of complex systems under consideration of imprecision is addressed. By joining two methods coming from different fields, namely, structural reliability and system reliability, a novel methodology ...
  • Implementing unitary 2-designs using random diagonal-unitary matrices 
    Nakata, Yoshifumi; Hirche, Christoph; Morgan, Ciara; Winter, Andreas (Schloss Dagstuhl- Leibniz-Zentrum für Informatik GmbH, Dagstuhl Publishing, 2015)
    Unitary 2-designs are random unitary matrices which, in contrast to their Haar-distributed counterparts, have been shown to be efficiently realized by quantum circuits. Most notably, unitary 2-designs are known to achieve ...
  • Inferring effective field observables from a discrete model 
    Bény, Cédric (Bristol : Institute of Physics Publishing, 2017)
    A spin system on a lattice can usually be modeled at large scales by an effective quantum field theory. A key mathematical result relating the two descriptions is the quantum central limit theorem, which shows that certain ...
  • Inverse determination of constitutive equations and cutting force modelling for complex tools using oxley's predictive machining theory 
    Denkena, Berend; Grove, Thilo; Dittrich, Marc-André; Niederwestberg, D.; Lahres, M. (Amsterdam : Elsevier, 2015)
    In analysis of machining processes, finite element analysis is widely used to predict forces, stress distributions, temperatures and chip formation. However, constitutive models are not always available and simulation of ...
  • Modeling and simulation of stochastically deformed waveguides using schelkunoff's method 
    Pham, Hoang Duc; Ploennigs, Soeren; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2018)
    This paper deals with the propagation of electromagnetic waves in cylindrical waveguides with irregularly deformed cross-sections. The general theory of electromagnetic waves is of high interest because of its practical ...
  • Multilayer ion trap technology for scalable quantum computing and quantum simulation 
    Bautista-Salvador, A.; Zarantonello, G.; Hahn, H.; Preciado-Grijalva, A.; Morgner, J.; Wahnschaffe, M.; Ospelkaus, C. (Bristol : Institute of Physics Publishing, 2019)
    We present a novel ion trap fabrication method enabling the realization of multilayer ion traps scalable to an in principle arbitrary number of metal-dielectric levels. We benchmark our method by fabricating a multilayer ...
  • The quantum technologies roadmap: A European community view 
    Acín, Antonio; Bloch, Immanuel; Buhrman, Harry; Calarco, Tommaso; Eichler, Christopher; Eisert, Jens; Esteve, Daniel; Gisin, Nicolas; Glaser, Steffen J.; Jelezko, Fedor; Kuhr, Stefan; Lewenstein, Maciej; Riedel, Max F.; Schmidt, Piet O.; Thew, Rob; Wallraff, Andreas; Walmsley, Ian; Wilhelm, Frank K. (Bristol : Institute of Physics Publishing, 2018)
    Within the last two decades, quantum technologies (QT) have made tremendous progress, moving from Nobel Prize award-winning experiments on quantum physics (1997: Chu, Cohen-Tanoudji, Phillips; 2001: Cornell, Ketterle, ...
  • Two-loop results on the renormalization of vacuum expectation values and infrared divergences in the FDH scheme 
    Gnendiger, Christoph; Signer, Adrian; Sperling, Marcus; Stöckinger, Dominik; Voigt, Alexander (Trieste : Proceedings of Science (PoS), 2014)
    Recent progress in the understanding of vacuum expectation values and of infrared divergences in different regularization schemes is reviewed. Vacuum expectation values are gauge and renormalization-scheme dependent ...
