Wavelength-versatile quantum key distribution for reconfigurable classical-quantum networks
Robert I. Woodward, Benjamin Griffiths, Yuen San Lo, J. F. Dynes, Andrew J. Shields · 2024
We report a high-speed GHz-clocked quantum key distribution (QKD) system, tunable over 65 nm using a novel injection-locked laser design. This paves the way to automatic optimsation of quantum channels in hybrid classical-quantum networks.
