How QKD Works
The technical foundations of Quantum Key Distribution: photon transmission, quantum key generation, and eavesdropping detection. Understand the security implications and limitations before deployment.
Quantum Technologies
Quantum Key Distribution
Expert lectures on QKD deployment, protocols, and security considerations. Case studies from defence, telecommunications, and enterprise drawn from practitioners who have shipped production QKD systems.
What the Lectures Cover
Each lecture runs approximately 20 minutes. Delivered by practitioners with direct experience of QKD projects in critical sectors. Recordings are available in the member archive.
QKD vs PQC
The key differences between QKD and Post-Quantum Cryptography. QKD relies on quantum physics to detect interception; PQC adapts classical algorithms to resist quantum attacks. Both have a role in defence strategy.
QKD Protocols
In-depth coverage of the protocols underlying QKD systems, including BB84 and E91. Learn how they leverage quantum mechanics to generate encryption keys and how they are applied in production environments.
QKD Companies and Vendors
Technical presentations from leading QKD vendors. Evaluate differences in technology approach, hardware architecture, and suitability for specific project requirements.
Real-World Case Studies
Practical examples of QKD deployed in defence networks, telecommunications, and enterprise environments. Covers project milestones, implementation challenges, and deployment outcomes.
QKD Research
The latest advances from leading research institutions actively building QKD systems. Covers groundbreaking protocols, novel hardware approaches, and emerging directions in quantum-secure communications.

QKD in the Security Landscape
Quantum Key Distribution uses the properties of quantum mechanics to detect any attempt to intercept a cryptographic key exchange. It does not replace existing encryption algorithms. It secures the key distribution process itself.
Deployment involves real engineering constraints: fibre distance limits, trusted node architecture, hardware cost, and integration with existing network infrastructure. The QSECDEF lecture series addresses these practical realities directly, rather than treating QKD as a theoretical technology.
The lectures are vendor-independent. QSECDEF does not favour any single supplier. Members evaluate vendor presentations alongside independent technical analysis to support their own procurement decisions.
Access the Full QKD Archive
All QKD lectures, vendor presentations, and case studies are available to QSECDEF members. Individual lifetime membership starts at $149. Corporate access for up to 10 users from $499 per year.
