Deployed trusted-node quantum key distribution over 300 km with a multi-core fiber access link
Martin Clason, Joakim Argillander, Didrik Bergström +8
Quantum key distribution (QKD) is increasingly considered for deployment in realistic communication networks, where long distances, heterogeneous fiber infrastructure, and coexiste…

Intermodal quantum key distribution field trial with active switching between fiber and free-space channels
Francesco Picciariello, Ilektra Karakosta-Amarantidou, Edoardo Rossi +6
Intermodal quantum key distribution enables the full interoperability of fiber networks and free-space channels, which are both necessary elements for the development of a global q…

Secure and robust randomness with sequential quantum measurements
Matteo Padovan, Giulio Foletto, Lorenzo Coccia +3
Quantum correlations between measurements of separated observers are crucial for applications like randomness generation and key distribution. Although device-independent security…
