  • Design of a speed meter interferometer proof-of-principle experiment 
    Gräf, Christian; Barr, B.W.; Bell, A.S.; Campbell, F.; Cumming, A.V.; Danilishin, S.L.; Gordon, N.A.; Hammond, G.D.; Hennig, J.; Houston, E.A.; Huttner, S.H.; Jones, R.A.; Leavey, Sean S.; Lück, Harald; Macarthur, J.; Marwick, M.; Rigby, S.; Schilling, R.; Sorazu, B.; Spencer, A.; Steinlechner, S.; Strain, Kenneth A.; Hild, Stefan (Bristol : IOP Publishing Ltd., 2014-11-07)
    The second generation of large scale interferometric gravitational wave (GW) detectors will be limited by quantum noise over a wide frequency range in their detection band. Further sensitivity improvements for future ...
  • Motional Fock states for quantum-enhanced amplitude and phase measurements with trapped ions 
    Wolf, Fabian; Shi, Chunyan; Heip, Jan C.; Gessner, Manuel; Pezzè, Luca; Smerzi, Augusto; Schulte, Marius; Hammerer, Klemens; Schmidt, Piet O. (London : Nature Publishing Group, 2019)
    The quantum noise of the vacuum limits the achievable sensitivity of quantum sensors. In non-classical measurement schemes the noise can be reduced to overcome this limitation. However, schemes based on squeezed or Schrödinger ...
  • Quantum noise cancellation in asymmetric speed metres with balanced homodyne readout 
    Zhang, T.; Knyazev, E.; Steinlechner, S.; Khalili, F.Y.; Barr, B. W.; Bell, A. S.; Dupej, P.; Briggs, J.; Graf, C.; Callaghan, J.; Hennig, J. S.; Houston, E. A.; Huttner, S. H.; Leavey, S.S.; Pascucci, D.; Sorazu, B.; Spencer, A.; Wright, J.; Strain, K.A.; Hild, S.; Danilishin, S.L. (Bristol : IOP Publishing Ltd., 2018)
    The Sagnac speed metre topology has been identified as a promising technique to reduce quantum back-action in gravitational-wave interferometers. However, imbalance of the main beamsplitter has been shown to increase the ...
  • The squeezed light source for the advanced virgo detector in the observation run O3 
    Mehmet, Moritz; Vahlbruch, Henning (Basel : Molecular Diversity Preservation International (MDPI), 2020)
    From 1 April 2019 to 27 March 2020, the Advanced Virgo detector, together with the two Advanced LIGO detectors, conducted the third joint scientific observation run O3, aiming for further detections of gravitational wave ...
