Deploying and validating a metropolitan QKD secure network: architecture and field performance
Claudia De Lazzari, Nicola Biagi, Damiano Giani +15
The advent of cryptographically relevant quantum computers poses an existential threat to classical public-key infrastructure. Quantum Key Distribution (QKD) addresses this challen…
Free-space time-bin encoded quantum key distribution from near- to mid-infrared wavelengths
Claudia De Lazzari, Tecla Gabbrielli, Natalia Bruno +9
Quantum technologies play a central role in establishing new ways of quantum-secured communication. We investigate Free-Space Quantum Communication and explore the advantage of imp…
Photon-by-photon quantum light state engineering
