Photon-number dependent afterpulsing in superconducting nanostrip single-photon detectors
Sebastian M. F. Raupach, Mariia Sidorova, Alexej D. Semenov
Superconducting nanostrip single-photon detectors (SNSPD) are wide-spread tools in photonic quantum technologies. Here, we study afterpulsing in commercial SNSPD made of amorphous…

Detection of ultra-weak laser pulses by free-running single-photon detectors: modeling dead time and dark counts effects
Hristina Georgieva, Alice Meda, Sebastian M. F. Raupach +6
In quantum communication systems, the precise estimation of the detector's response to the incoming light is necessary to avoid security breaches. The typical working regime uses a…

Combining fiber Brillouin amplification with a repeater laser station for fiber-based optical frequency dissemination over 1400 km
Sebastian Koke, Alexander Kuhl, Thomas Waterholter +7
We investigate optical frequency dissemination over a 1400 km long fiber link in looped configuration over a pair of underground fibers between Braunschweig and Strasbourg. This fi…
