  • Bell Inequalities for Graph States 
    Gühne, Otfried; Tóth, Géza; Hyllus, Philipp; Briegel, Hans J. (College Park, Md. : APS, 2005)
    We investigate the nonlocal properties of graph states. To this aim, we derive a family of Bell inequalities which require three measurement settings for each party and are maximally violated by graph states. In turn, for ...
  • Bounded Entanglement Entropy in the Quantum Ising Model 
    Grimmett, Geoffrey R.; Osborne, Tobias J.; Scudo, Petra F. (Heidelberg : Springer, 2020)
    A rigorous proof is presented of the boundedness of the entanglement entropy of a block of spins for the ground state of the one-dimensional quantum Ising model with sufficiently strong transverse field. This is proved by ...
  • Detecting quantum entanglement : entanglement witnesses and uncertainty relations 
    Gühne, Otfried (Hannover : Universität, 2004)
    [no abstract]
  • Entanglement Capability of Two-qubit Operations 
    Kraus, B.; Dür, W.; Vidal, G.; Cirac, J.I.; Lewenstein, M.; Linden, N.; Popescu, S. (Berlin : De Gruyter, 2001)
    We study the optimal way of creating bi-partite entanglement using a general two-qubit interaction. On the one hand, we analyze the entanglement capability of an arbitrary non-local Hamiltonian acting on two qubits. We ...
  • Quantum technologies in space 
    Kaltenbaek, Rainer; Acin, Antonio; Bacsardi, Laszlo; Bianco, Paolo; Bouyer, Philippe; Diamanti, Eleni; Marquardt, Christoph; Omar, Yasser; Pruneri, Valerio; Rasel, Ernst M.; Sang, Bernhard; Seidel, Stephan; Ulbricht, Hendrik; Ursin, Rupert; Villoresi, Paolo; van den Bossche, Mathias; Klitzing, Wolf von; Zbinden, Hugo; Paternostro, Mauro; Bassi, Angelo (Dordrecht [u.a.] : Springer Science + Business Media B.V., 2021)
    Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitigate some of the biggest challenges facing ...
