  • Steinlechner, Jessica; Ast, Stefan; Krueger, Christoph; Singh, Amrit Pal; Eberle, Tobias; Haendchen, Vitus; Schnabel, Roman (Basel : Mdpi Ag, 2013-01)
    The efficient generation of second-harmonic light and squeezed light requires non-linear crystals that have low absorption at the fundamental and harmonic wavelengths. In this work the photo-thermal self-phase modulation ...
  • Apellaniz, Iagoba; Lücke, Bernd; Peise, Jan; Klempt, Carsten; Toth, Geza (Bristol : IOP Publishing Ltd., 2015-08-13)
    We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measurement of the sensitivity. Our method ...
  • Eberle, Tobias; Haendchen, Vitus; Duhme, Jörg; Franz, Torsten; Furrer, Fabian; Schnabel, Roman; Werner, Reinhard F. (Bristol : IOP Publishing Ltd., 2013-05-30)
    We report the suitability of an Einstein-Podolsky-Rosen entanglement source for Gaussian continuous-variable quantum key distribution at 1550 nm. Our source is based on a single continuous-wave squeezed vacuum mode combined ...
  • Ahlbrecht, Andre; Alberti, Andrea; Meschede, Dieter; Scholz, Volkher B.; Werner, Albert H.; Werner, Reinhard F. (Bristol : IOP Publishing Ltd., 2012)
    We show that the presence of an interaction in the quantum walk of two atoms leads to the formation of a stable compound, a molecular state. The wave function of the molecule decays exponentially in the relative position ...
  • Hage, B.; Franzen, A.; DiGuglielmo, J.; Marek, P.; Fiurasek, Jaromir; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on Gaussian operations. Here, we make use ...
  • Klempt, Carsten; Topic, O.; Gebreyesus, G.; Scherer, M.; Henninger, T.; Hyllus, P.; Ertmer, Wolfgang; Santos, Luis; Arlt, Jan J. (College Park : American Physical Society, 2010)
    Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplification of vacuum fluctuations for matter waves ...
  • Zhao, Jing; Lein, Manfred (Bristol : IOP Publishing Ltd., 2012)
    In this paper, autoionizing states in the one-dimensional helium atom are investigated by numerical solution of the time-dependent two-electron Schrodinger equation. The atom is irradiated by an extreme ultraviolet (XUV) ...
  • Vahlbruch, H.; Chelkowski, S.; Danzmann, Karsten; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    We report the experimental realization of squeezed quantum states of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier frequency band down to 1 Hz have been ...
  • Schnabel, Roman; Mavalvala, Nergis; McClelland, David E.; Lam, Ping K. (London : Nature Publishing Group, 2010)
    Einstein's general theory of relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves (GWs) have ...
  • Horst, Ina; Heimann, Louisa; Peterhansel, Christoph (Abingdon : Taylor and Francis Ltd., 2013)
    Gene promoters perceive numerous signals and integrate this information into a single response, the transcriptional activity of a gene. It was speculated that covalent modification of histones on the promoters might have ...
