Use cases
Two physical channels.
One principle.
The same physical principle on metropolitan fibre and on links between orbit and ground: CV-QKD in fibre, DV-QKD from space.
Terrestrial networks
QKD over the fibre you already have.
Metropolitan fibre carries some of the most sensitive traffic there is: interbank transactions, government data, clinical records, industrial control signals. Our CV-QKD systems run over standard single-mode fibre at 1550 nm, adding quantum key distribution on top of today’s encrypted channels.
Sectors
Where secrets don’t expire.
Financial sector
Interbank transactions, mirrored data centres and stock-exchange communications with confidentiality requirements measured in decades.
Government and defence
Sovereign government networks and classified communications, where retroactive interception is a national-security risk.
Healthcare
Medical records and genomic data: personal data that stays sensitive for decades (GDPR / NIS2).
Telecom operators
Quantum key services as a value-added layer on existing metropolitan fibre, designed for shared rather than dedicated fibre.
Critical infrastructure
Energy, water and transport: telemetry and industrial control signals secured against retroactive interception.
Satellite networks · ground segment
Bridging orbit and network.
Fibre is bound by geography. Optical satellite-to-ground links are the scalable route to intercontinental QKD, with the satellite replacing long chains of ground relay nodes. Q-Dynamics develops the ground-segment hardware for discrete-variable QKD (DV-QKD) reception at optical ground stations (OGS): polarisation analysis and front-end processing of single-photon signals from low Earth orbit (LEO).
European framework
EuroQCI.
The European Quantum Communication Infrastructure (EuroQCI) will deploy a continent-wide network of quantum-secure terrestrial and satellite links. Q-Dynamics systems, CV-QKD over fibre and the OGS Quantum Stack in the ground segment, are designed to fit that architecture.
