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…

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…
