Quantum Key Distribution in-field implementations: Technology assessment of QKD deployments

JRC technical report (EUR 29865 EN, Travagnin and Lewis) surveying quantum key distribution deployed outside the laboratory, covering terrestrial and satellite networks funded publicly or privately. It updates the earlier JRC quantum communications report, discusses limits on distance, key rate and fibre compatibility, and was prepared as part of the study defining a vision for a European quantum communication infrastructure. Lab-scale research and one-off small pilots are excluded.
