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…
