ESA's QKDSat Mission Qualifies Quantum Laser Component for Secure Communications

The Quantum Faint Pulse Source (FPS), a key component for ESA's QKDSat mission, has successfully completed its qualification. This technology is vital for enabling secure satellite-based Quantum Key Distribution (QKD) services, which use quantum physics to encrypt messages from space. This advancement aims to enhance resilient and quantum-secure connectivity across Europe.
