DeepSec 2026 Talk: Quantum Communication – Andreas Neuhold
Quantum computers will break the encryption we rely on today, and the clock is ticking. But what does that actually mean, and what can you do about it right now? This talk starts from the ground up, giving attendees an accessible introduction to the two quantum-safe building blocks: Post-Quantum Cryptography (PQC), a mathematical software-based replacement for classical key exchange, and Quantum Key Distribution (QKD), a physics-based approach that uses quantum optical channels to distribute keys with information-theoretic security. This talk cuts through the hype and delivers a technically grounded, practitioner-focused view of what quantum-safe communication actually means in 2026 and what you can deploy right now. Whether you are a security engineer, network architect, or technical decision-maker, this session provides the concrete technical foundation needed to assess, plan, and implement quantum-resistant communication today.
