Rack-integrated quantum dot-based source of single and entangled photons at telecom C-band
Michal Vyvlecka, Raphael Joos, Benjamin Breiholz +8
For quantum light sources in everyday telecommunication networks, quantum science needs to be fully transformed into quantum technology. The first necessary step to move outside a…
A complete fs-laser-ablation route to miniaturized single-crystal PMN-PT piezoelectric actuators
Menotti Markovic, Lucia Oberndorfer, Tobias M. Krieger +15
This article presents a novel fabrication route for miniaturized piezoelectric actuators that relies exclusively on processes based on femtosecond (fs) laser ablation. Previous wor…
Time-bin encoded quantum key distribution over 120 km with a telecom quantum dot source
Jipeng Wang, Joscha Hanel, Zenghui Jiang +11
Quantum key distribution (QKD) with deterministic single photon sources has been demonstrated over intercity fiber and free-space channels. The previous implementations relied main…
Ultrastable, low-error dynamic polarization encoding of deterministically generated single photons
Joscha Hanel, Zenghui Jiang, Jipeng Wang +10
The ability to inscribe information on single photons at high speeds is a crucial requirement for quantum applications such as quantum communication and measurement-based photonic…
Asymmetric two-photon response of an incoherently driven quantum emitter
Lennart Jehle, Lena M. Hansen, Patrik I. Sund +7
Quantum emitters promise to emit exactly one photon with high probability when pumped by a laser pulse. However, even in ideal systems, re-excitation during a laser pulse causes th…
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…
