Deploying and validating a metropolitan QKD secure network: architecture and field performance
Claudia De Lazzari, Nicola Biagi, Damiano Giani +15
The paper reports the deployment and experimental validation of a metropolitan‑scale quantum key distribution (QKD) network in Milan, integrating QKD hardware, standards‑compliant…
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
Nicola Biagi, Saverio Francesconi, Alessandro Zavatta +1
The ability to manipulate light at the level of single photons, its elementary excitation quanta, has recently made it possible to produce a rich variety of tailor-made quantum sta…
Entangling macroscopic light states by delocalized photon addition
Nicola Biagi, Luca S. Costanzo, Marco Bellini +1
We present the experimental generation of tunable entanglement between distinct field modes by the delocalized addition of a single photon. We show that one can preserve a high deg…
