The Race to Encrypt Before Quantum Computers Break Everything
Data encrypted today, right now, can be intercepted and stored - not broken, just kept - until a computer capable of breaking it exists. That strategy has a name, 'harvest now, decrypt later', and it is why the migration to quantum-safe encryption is already running flat out, years before anyone has built a quantum computer that can actually do the breaking.
The video explains why today's public-key encryption (RSA, Diffie-Hellman, elliptic-curve cryptography) depends on factoring and discrete logarithms being too slow for an ordinary computer; how Peter Shor's 1994 algorithm, developed at Bell Labs, proved a quantum computer could do both quickly; and how far real quantum hardware - including Google's Willow chip (9 Dec 2024) - actually is from the roughly one million noisy qubits a 2025 Google estimate says breaking RSA-2048 would need.
Then post-quantum cryptography itself: lattice-based and hash-based mathematics that runs on ordinary computers, not quantum ones, and NIST's standards - FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA), finalised 13 August 2024, plus HQC, selected as a backup algorithm on 11 March 2025. The video also separates PQC from quantum key distribution (QKD), using Romania's RoNaQCI network (announced 27 February 2026) and Malta's live PRISM link (May 2026) to show the difference between QKD's specialised fibre hardware and PQC's ordinary software.
The policy side: the NSA's Commercial National Security Algorithm Suite 2.0 (announced September 2022) and Executive Order 14412, signed 22 June 2026, which set US federal deadlines of 2030 and 2031; the European Commission's June 2025 roadmap; and Tsinghua University cryptographer Wang Xiaoyun's March 2026 remarks on China's own, disputed technical approach.
Finally, what migration actually requires beyond a browser update, the genuine disagreements over key size, algorithm maturity and timeline that remain unresolved, and what any of this means for governments, large organisations and individuals - general information, not personal advice.
