  • A transportable optical lattice clock for metrology and geodesy 
    Grotti, Jacopo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    This work presents the first measurement campaigns performed with PTB transportable optical lattice clock based on Strontium atoms for applications in clock comparisons and relativistic geodesy.
  • An aluminum optical clock setup and its evaluation using Ca+ 
    Kramer, Johannes Albrecht (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    This thesis reports about the progress of the aluminum ion clock that is set up at the German National Metrological Institute, Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig. All known relevant systematic ...
  • Auxiliary function development for the LISA metrology system 
    Brause, Nils Christopher (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    The Laser Interferometer Space Antenna (LISA) is a planned gravitational wave detector to be positioned in space. It consists of three spacecrafts that use Long Range Interferometry (LRI) to measure relative distance changes ...
  • Controlling motion in quantum logic clocks 
    Wübbena, Jannes Bernhard (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2014)
    [no abstract]
  • Detecting Multiparticle Entanglement of Dicke States 
    Lücke, Bernd; Peise, Jan; Vitagliano, Giuseppe; Arlt, Jan J.; Santos, Luis; Toth, Geza; Klempt, Carsten (College Park : American Physical Society, 2014)
    Recent experiments demonstrate the production of many thousands of neutral atoms entangled in their spin degrees of freedom. We present a criterion for estimating the amount of entanglement based on a measurement of the ...
  • A novel, robust quantum detection scheme 
    Hemmerling, Boerge; Gebert, Florian; Wan, Yong; Schmidt, Piet O. (Bristol : IOP Publishing Ltd., 2012)
    Protocols used in quantum information and precision spectroscopy rely on efficient internal quantum state discrimination. With a single ion in a linear Paul trap, we implement a novel detection method which utilizes ...
  • Traceability of the Hannover FG5X-220 to the SI units 
    Schilling, Manuel; Timmen, Ludger (Cham : Springer, 2016-06-28)
    The absolute measurement of g is currently realized through the laser interferometric measurement of a free falling retro-reflector. The Micro-g LaCoste FG5X is a free-fall gravimeter with a laser interferometer in ...
