6GQuCryptoLab leads research in quantum optical communications for the deployment of secure networks on Earth and in space.

The infrastructure uses entangled photon sources to test optical channels and simulate satellite links under real atmospheric turbulence conditions. Its vision is to act as a strategic catalyst for integrating satellites as active nodes in a global quantum network, protecting critical infrastructure against future computational threats.

Use Cases

  • Satellites as range extenders for end-to-end QKD networks: An ultra-secure defense network combining terrestrial and satellite QKD with a “flying node” for long distance. It implements hybrid protocols (QKD/PQC) and multi-user communications (QCKA) through VPN tunnels. The entire system is validated with advanced simulators (DSS-Sim, QKDNetSim) in the QuantumLab to shield critical infrastructures against quantum threats.
  • Quantum-secured satellite networks: Establishes ultra-secure satellite communications by protecting the control channel (TT&C) using QKD (Quantum Key Distribution). It combines radio-frequency (RF) and optical signals with improved pointing systems (PAT) to provide a robust hybrid connection. It uses post-quantum cryptography (PQC) specifically for user and device authentication. The entire system is managed via a KMS (Key Management System) compliant with the ETSI-014 standard. Physical and algorithmic security are integrated to ensure the integrity of space infrastructures.
