Keynote: Post Quantum Future
summary
Separates hype from current European work, explains Google’s quantum supremacy as a benchmark not apocalypse, and claims a viable universal quantum computer that can run Shor's algorithm could arrive in roughly a decade and reduce billion‑year factorizations to seconds. Distinguishes D‑Wave annealers from universal machines, reports a working quantum key distribution link between The Hague and Rotterdam and free‑space QKD at 144 km, notes China’s satellite and 2,000 km backbone, and describes a live post‑quantum VPN using CRYSTALS‑Kyber while urging key‑inventory, larger keys, and phased migration.
