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…
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…
Universal Composite Pulses for Efficient Population Inversion with an Arbitrary Excitation Profile
Genko T. Genov, Marcel Hain, Nikolay V. Vitanov +1
We introduce a method to rotate arbitrarily the excitation profile of universal broadband composite pulse sequences for robust high-fidelity population inversion. These pulses comp…
Roadmap on STIRAP applications
Klaas Bergmann, Hanns-Christoph Nägerl, Cristian Panda +31
STIRAP (Stimulated Raman Adiabatic Passage) is a powerful laser-based method, usually involving two photons, for efficient and selective transfer of population between quantum stat…
