Motion-induced directionality of collective emission in a non-chiral waveguide
Yoan Spahn, Jens Hartmann, Benedikt Saalfrank +3
We report the experimental observation of motion-induced directionality in collective atomic emission within a hollow-core waveguide, establishing a general principle: directional…
Practical quantum tokens: challenges and perspectives
Nadezhda P. Kukharchyk, Holger Boche, Christian Deppe +21
The concept of quantum tokens dates back alongside quantum cryptography to Stephen Wiesner's seminal work in 1983[1]. Already this initial work proposes society-relevant applicatio…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
Ultrabright and narrowband intra-fiber biphoton source at ultralow pump power
Alexander Bruns, Chia-Yu Hsu, Sergiy Stryzhenko +5
Nonclassical photon sources of high brightness are key components of quantum communication technologies. We here demonstrate the generation of narrowband, nonclassical photon pairs…
Spatially strongly confined atomic excitation via two dimensional stimulated Raman adiabatic passage
Hamid R. Hamedi, Giedrius Zlabys, Veronica Ahufinger +3
We consider a method of sub-wavelength superlocalization and patterning of atomic matter waves via a two dimensional stimulated Raman adiabatic passage (2D STIRAP) process. An atom…
Loading and spatially-resolved characterization of a cold atomic ensemble inside a hollow-core fiber
Thorsten Peters, Leonid P. Yatsenko, Thomas Halfmann
We present a thorough experimental investigation of the loading process of laser-cooled atoms from a magneto-optical trap into an optical dipole trap located inside a hollow-core p…
