A High-frequency Geodetic VLBI Experiment for Optical Clock Comparison
Monia Negusini, Myoung-Sun Heo, Cecilia Clivati +40
An intercontinental metrological clock comparison between Italy and the Republic of Korea was performed by means of geodetic K-band VLBI observations. The comparison involved the h…
Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
Hybrid optical sensor for combined thermal and dimensional monitoring in laser processing
Simone Donadello
Optical measurements enable non-contact and high-speed monitoring of physical processes, offering a non-invasive and versatile approach across a wide range of fields, from scientif…
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…

Monitoring of laser metal deposition height by means of coaxial laser triangulation
Simone Donadello, Maurizio Motta, Ali Gökhan Demir +1
Laser metal deposition (LMD) is an additive manufacturing technique, whose performances can be influenced by several factors and parameters. Monitoring their evolution allows for a…
Probing multipulse laser ablation by means of self-mixing interferometry
Simone Donadello, Ali Gökhan Demir, Barbara Previtali
In this work, self-mixing interferometry (SMI) is implemented inline to a laser microdrilling system to monitor the machining process by probing the ablation-induced plume. An anal…
