Rate-adaptive Reconciliation for Experimental Continuous-variable Quantum Key Distribution with Discrete Modulation over a Free-space Optical Link
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +8
Continuous-variable quantum key distribution (CV-QKD) has been proposed as a method for securely exchanging keys to protect against the security concerns caused by potential advanc…
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…
Adaptive Reconciliation for Experimental Continuous-Variable Quantum Key Distribution Over a Turbulent Free-Space Optical Channel
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +5
We experimentally demonstrate adaptive reconciliation for continuous-variable quantum key distribution over a turbulent free-space optical channel. Additionally, we propose a metho…
