Quantum Satellite Communications
How satellites distribute quantum cryptographic keys using polarised photons and entangled particle pairs. The security guarantees, detection mechanisms, and fundamental limits of space-based QKD.
Quantum Technologies
Quantum Satellites
Space-based quantum communications: QKD from orbit, quantum sensing for Earth observation, and the engineering realities of building secure satellite infrastructure. Expert lectures from ESA, Airbus, and leading QSAT organisations.
What the Lectures Cover
Each lecture runs approximately 20 minutes. Delivered by engineers and researchers with direct experience of quantum satellite programmes. Includes both technical deep-dives and strategic overviews of the QSAT landscape.
Entanglement and Teleportation
Quantum entanglement as the basis for advanced satellite communications. How quantum teleportation enables secure relay of quantum information across vast distances without physical transport of particles.
Quantum Sensing for Space
Applications of quantum sensing in Earth observation and navigation. Ultra-precise measurement capabilities enabled by quantum technologies and their use in positioning, navigation, and timing (PNT) systems.
Security Vulnerabilities
Practical security challenges in quantum satellite systems: hardware vulnerabilities, signal attenuation, trusted ground station architecture, jamming risks, and regulatory constraints on orbital systems.
Space Industry Players
Companies and organisations building quantum communications satellite infrastructure. Technology differences, current capability levels, and project timelines from organisations including ESA, Airbus, and sector specialists.
6G and Future Networks
The intersection of quantum satellite communications with 6G network architecture. How space-based quantum links support global secure connectivity and interplanetary data exchange.

Securing Communications from Orbit
Ground-based fibre QKD networks face distance limits. Trusted nodes introduce vulnerabilities. Satellite-based QKD addresses both by distributing entangled photons or quantum keys over intercontinental distances without intermediate trusted nodes.
China's Micius satellite demonstrated the technical feasibility of satellite QKD in 2017. European programmes, including work at ESA and through the EuroQCI initiative, are advancing the engineering required for operational deployment. The lecture series tracks this progress through direct contributions from people working on these programmes.
Alongside communications security, quantum sensing from space offers unprecedented precision for positioning, navigation, and timing applications. These capabilities have direct implications for defence, critical infrastructure, and resilient global communications networks.
