  • 0.75 atoms improve the clock signal of 10,000 atoms 
    Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • All-optical coherent quantum-noise cancellation in cascaded optomechanical systems 
    Schweer, Jakob; Steinmeyer, Daniel; Hammerer, Klemens; Heurs, Michèle (Woodbury, NY : Inst., 2022)
    Coherent quantum-noise cancellation (CQNC) can be used in optomechanical sensors to surpass the standard quantum limit (SQL). In this paper, we investigate an optomechanical force sensor that uses the CQNC strategy by ...
  • Coherent cancellation of backaction noise in optomechanical force measurements 
    Wimmer, Maximilian H.; Steinmeyer, Daniel; Hammerer, Klemens; Heurs, Michèle (College Park, MD : American Physical Society, 2014)
    Optomechanical detectors have reached the standard quantum limit in position and force sensing where measurement backaction noise starts to be the limiting factor for the sensitivity. A strategy to circumvent measurement ...
  • Designs of the frequency reference cavity for the AEI 10 m Prototype interferometer 
    Kawazoe, Fumiko; Taylor, John Robert; Bertolini, Alessandro; Born, Michael; Chen, Yanbei; Dahl, Katrin; Gering, Daniel; Goßler, Stefan; Gräf, Christian; Heinzel, Gerhard; Hild, Stefan; Kranz, Oliver; Kühn, Gerrit; Lück, Harald; Mossavi, Kasem; Schnabel, Roman; Somiya, Kentaro; Strain, Kenneth A.; Wanner, Alexander; Westphal, Tobias; Willke, Benno; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2010)
    The AEI 10 m Prototype is in its designing phase and will provide a test-bed for very sensitive interferometric experiments, such as the sub-SQL interferometer. It will test new techniques to reach - and even surpass - the ...
  • Phase magnification by two-axis countertwisting for detection-noise robust interferometry 
    Anders, Fabian; Pezze, Luca; Smerzi, Augusto; Klempt, Carsten (College Park : American Physical Society, 2018)
    Entanglement-enhanced atom interferometry has the potential of surpassing the standard quantum limit and eventually reaching the ultimate Heisenberg bound. The experimental progress is, however, hindered by various technical ...
