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…
Measurement and control of the interaction frequency shift in bosonic optical lattice clocks
J. P. Salvatierra, M. Barbiero, G. Bertaina +3
We report precise measurements of inter-level interactions in a bosonic optical lattice clock based on Sr atoms. We observe a nonlinear density dependence of the clock shift…
International Optical Clock Comparison Using the European Optical Fiber Network
Marco Pizzocaro, Clara Zyskind, Anne Amy-Klein +41
Optical clocks have achieved remarkable estimated fractional frequency uncertainties reaching the level and below, enabling applications in fundamental physics, general…
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…
Roadmap towards the redefinition of the second
N. Dimarcq, M. Gertsvolf, G. Mileti +34
This paper outlines the roadmap towards the redefinition of the second, which was recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the…
Seismic monitoring using the telecom fiber network
Simone Donadello, Cecilia Clivati, Aladino Govoni +11
Laser interferometry enables to remotely measure microscopical length changes of deployed telecommunication cables originating from earthquakes. Long range and compatibility with d…
