Nonlinear and Quantum Optics with Whispering Gallery Resonators Revisited
Dmitry V. Strekalov, Nicholas J. Lambert, Christoph Marquardt +5
In 2016 we published a review paper "Nonlinear and Quantum Optics with Whispering Gallery Resonators" (1). While writing this review, we found it often necessary to defer addressin…
Removal of guided acoustic wave Brillouin scattering to the quantum-noise limit using symmetric interferometry in twisted photonic crystal fibers
Vishal Choudhury, Kevin Jaksch, Markus Lippl +3
Guided acoustic wave Brillouin scattering (GAWBS) is a major obstacle in fiber-based quantum and high-speed classical communication systems as well as in interferometry. The transv…
Narrowband Frequency-Entangled Photon Source for Hong-Ou-Mandel Interferometry
Yen-Ju Chen, Sheng-Hsuan Huang, Thomas Dirmeier +5
Hong-Ou-Mandel (HOM) interferometry with entangled photons exhibits distinctive quantum features. By introducing frequency entanglement (discrete-color entangled states) into HOM i…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Klaus Blaum, Peter Kaufmann, Jochen Kronjäger +168
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…
Indistinguishable MHz-narrow heralded photon pairs from a whispering gallery resonator
Sheng-Hsuan Huang, Thomas Dirmeier, Golnoush Shafiee +5
Hong-Ou-Mandel interference plays a vital role in many quantum optical applications where indistinguishability of two photons is important. Such photon pairs are commonly generated…
Ad-hoc hybrid-heterogeneous metropolitan-range quantum key distribution network
Matthias Goy, Jan Krause, Ãmer Bayraktar +37
This paper presents the development and implementation of a versatile ad-hoc metropolitan-range Quantum Key Distribution (QKD) network. The approach presented integrates various ty…
