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…
Towards fully-fledged quantum and classical communication over deployed fiber with up-conversion module
Davide Bacco, Ilaria Vagniluca, Daniele Cozzolino +7
Quantum key distribution (QKD), the distribution of quantum secured keys useful for data encryption, is expected to have a crucial impact in the next decades. However, although the…
Coherent phase transfer for real-world twin-field quantum key distribution
Cecilia Clivati, Alice Meda, Simone Donadello +10
Quantum mechanics allows the distribution of intrinsically secure encryption keys by optical means. Twin-field quantum key distribution is the most promising technique for its impl…
Passively stable distribution of polarisation entanglement over 192 km of deployed optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +14
Quantum key distribution (QKD) based on entangled photon pairs holds the potential for repeater-based quantum networks connecting clients over long distance. We demonstrate long-di…
Field trial of a finite-key quantum key distribution system in the Florence metropolitan area
Davide Bacco, Ilaria Vagniluca, Beatrice Da Lio +8
In-field demonstrations in real-world scenarios boost the development of a rising technology towards its integration in existing infrastructures. Although quantum key distribution…
In-field entanglement distribution over a 96 km-long submarine optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +13
Techniques for the distribution of quantum-secured cryptographic keys have reached a level of maturity allowing them to be implemented in all kinds of environments, away from any f…
Realization of a twin beam source based on four-wave mixing in Cesium
G. Adenier, D. Calonico, S. Micalizio +3
Four-wave mixing (4WM) is a known source of intense non-classical twin beams. It can be generated when an intense laser beam (the pump) and a weak laser beam (the seed) overlap in…
The Space Optical Clocks Project: Development of high-performance transportable and breadboard optical clocks and advanced subsystems
S. Schiller, A. Görlitz, A. Nevsky +28
The use of ultra-precise optical clocks in space ("master clocks") will allow for a range of new applications in the fields of fundamental physics (tests of Einstein's theory of Ge…
