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…
Practical quantum secure direct communication with squeezed states
Iris Paparelle, Faezeh Mousavi, Francesco Scazza +3
Quantum secure direct communication (QSDC) is a rapidly developing quantum communication approach, where secure information is directly transmitted, providing an alternative to key…
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…
Time-bin encoding quantum key distribution in free-space horizontal links during nighttime and daytime
Sebastiano Cocchi, Domenico Ribezzo, Giulia Guarda +4
Free-space quantum key distribution (QKD) represents a groundbreaking advancement in secure communication, enabling secure key exchange over vast distances and offering robust encr…
