  • 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 ...
  • 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.
  • 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 ...
  • 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 ...
  • 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 ...
