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…
Light Field Ghost Imaging
Alberto Paniate, Gianlorenzo Massaro, Alessio Avella +5
Techniques based on classical and quantum correlations in light beams, such as ghost imaging, allow us to overcome many limitations of conventional imaging and sensing protocols. D…
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…
