Spectral evolution of two-photon emission in microresonators
Francesca Famà, Stefano Dello Russo, Stefano Giaccari +14
High-Q silicon nitride microresonators are versatile sources for generating photon pairs via four-wave mixing. We investigate the spectral coherence of this process, tracking the t…
QKD protected fiber-based infrastructure for time dissemination
Alice Meda, Alberto Mura, Salvatore Virzì +10
In this study, we demonstrate the possibility to protect, with Quantum Key Distribution (QKD), a critical infrastructure as the fiber-based one used for time and frequency (TF) dis…
Detection Efficiency Characterization for Free-Space Single-Photon Detectors: Measurement Facility and Wavelength-Dependence Investigation
Salvatore Virzì, Alice Meda, Elisa Redolfi +4
In this paper, we present a new experimental apparatus for the measurement of the detection efficiency of free-space single-photon detectors based on the substitution method. For t…
Phase Noise in Real-World Twin-Field Quantum Key Distribution
Gianluca Bertaina, Cecilia Clivati, Simone Donadello +9
The impact of noise sources in real-world implementations of Twin-Field Quantum Key Distribution (TF-QKD) protocols is investigated, focusing on phase noise from photon sources and…
Unexpected detection rate dependence of the intrinsic detection efficiency in single-photon detectors based on avalanche diodes
Sebastian M. F. Raupach, Ivo Pietro Degiovanni, Hristina Georgieva +6
Single-photon detectors are a pivotal component in photonic quantum technologies. A precise and comprehensive calibration of the intrinsic detection efficiency is of utmost importa…
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…
