  • Broadband detection of 18 teeth in an 11-dB squeezing comb 
    Wilken, Dennis; Junker, Jonas; Heurs, Michèle (College Park, Md. [u.a.] : American Physical Society, 2024)
    Squeezed vacuum is a versatile resource of bipartite entanglement for quantum metrology and information. Optical parametric oscillators generate these states in a frequency comb structure. We show the simultaneous detection ...
  • 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 ...
  • Exploring Interacting Quantum Many-Body Systems by Experimentally Creating Continuous Matrix Product States in Superconducting Circuits 
    Eichler, C.; Mlynek, J.; Butscher, J.; Kurpiers, P.; Hammerer, K.; Osborne, T.J.; Wallraff, A. (College Park, ML : American Physical Society, 2015)
    Improving the understanding of strongly correlated quantum many-body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern condensed matter physics, materials research, ...
  • Fundamental frontiers of quantum science and technology 
    Arndt, Markus; Bassi, Angelo; Giulini, Domenico; Heidmann, Antoine; Raimond, Jean-Michel (Amsterdam [u.a.] : Elsevier, 2011)
    We discuss recent studies on the foundations of quantum physics with photonic, atomic, molecular and micromechanical systems as well as theoretical treatments of the interface between quantum physics and classical observations. ...
  • 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 ...
