Noise characterization for co-propagation of classical and CV-QKD signals over fiber and free-space link
João dos Reis Frazão, Vincent van Vliet, Kadir Gümüş +5
Real-time CV-QKD receiver achieves peak 2.9 Mbit/s secret-key-rates over 12.8 km of fiber, while co-propagating 15 classical channels, separated 1 nm from the quantum signal. Perfo…

Co-propagation of Classical and Continuous-variable QKD Signals over a Turbulent Optical Channel with a Real-time QKD Receiver
João dos Reis Frazão, Vincent van Vliet, Sjoerd van der Heide +5
We demonstrate classical and quantum signal co-propagation over a turbulent free-space channel with 3 Tbit/s throughput and record 2.7 Mbit/s secret-key rate. Our real-time GPU-bas…
