Wavelength-versatile quantum key distribution for reconfigurable classical-quantum networks

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.
