Getting Started With Quantum Readiness and PQC Migration This page collects the PostQuantum.com articles you need to kick‑off and run a quantum‑readiness program, end‑to‑end.

PQC migration is a program, not a patch. I just updated my curated quantum readiness starting list — from "what's the threat?" to "how do we run this like a real program?"

Switzerland Just Published the Quietest Quantum Strategy in Europe. It Might Be the Smartest. Switzerland publishes its first national quantum strategy, betting on open collaboration and ecosystem depth over big-spend national champions.

Switzerland's first quantum strategy just dropped and it might be the most refreshingly honest national quantum document I've read.

No hype. The bet: don't race - be the place everyone wants to build.

Think CERN, but for the quantum stack.

No Single Law, No Single Excuse: How Canada Regulates PQC Without Saying “Quantum” Canada's visible PQC guidance - three documents published mid-2025 - is just the tip. Beneath it sits a layered enforcement framework spanning financial regulation, critical infrastructure law, privacy...

Canada's post-quantum readiness isn't just three guidance docs — it's a layered regulatory stack (OSFI, CCSPA, PIPEDA, critical‑infrastructure & securities rules) that compels PQC adoption even without saying “quantum.” Essential read for CISOs. #QuantumSecurity #PQC

Google’s Merkle Tree (MTC) Gambit to Quantum-Proof HTTPS Google will not put post-quantum signatures into traditional X.509 certificates for Chrome. Instead, the company announced in February 2026 a fundamentally different architecture - Merkle Tree Certificates...

Google's Merkle Tree Certificates (MTCs) could make post‑quantum HTTPS smaller than today’s TLS chains—cutting auth data from ~14.7 KB to ~736 B. Built with Cloudflare and heading to IETF PLANTS. Big win — and a browser‑centralization risk. Read: postquantum.com/security-pqc... #PQC #TLS

The “Cybersecurity Apocalypse in 2026” and the Jesse–Victor–Gharabaghi (JVG) Algorithm: Why This Claim Doesn’t Hold Up A preprint manuscript (ID: 202510.1649) titled “A Novel Hybrid Quantum Circuit for Integer Factorization: End-to-End Evaluation in Simulation and Real Quantum Hardware” was published on the Preprints....

“Cybersecurity Apocalypse in 2026” is back - now tied to the Jesse–Victor–Gharabaghi (JVG) algorithm preprint. I published a technical reality check: postquantum.com/security-pqc...

My take: another day, another (very) unfounded quantum cyber‑apocalypse claim.

Pinnacle Architecture: 100,000 Qubits to Break RSA-2048, but at What Cost? Iceberg Quantum's Pinnacle Architecture paper claims RSA-2048 can be factored with fewer than 100,000 physical qubits - a genuine 10× reduction over the previous state of the art - by replacing surfac...

I promised a deep-dive on the Pinnacle Architecture paper after my initial analysis. Media's still running hype cycles.

Enterprise PQC Migration: New Study Predicts 5–15+ Year Timelines A new peer-reviewed study titled 'Enterprise Migration to Post-Quantum Cryptography: Timeline Analysis and Strategic Frameworks' by independent researcher Robert Campbell has been published in the open-access...

New peer‑reviewed study (Computers, MDPI) by Robert Campbell finds enterprise migration to post‑quantum cryptography will take years — ~5–7y (small), 8–12y (medium), 12–15+y (large). It’s an ecosystem-wide transformation. Start preparing: postquantum.com/security-pqc... #PQC #QuantumSecurity

NIS2, DORA, and the EU Post-Quantum Roadmap If you are a CISO under NIS2 or DORA, you are already expected to run a risk-management system that tracks material, evolving threats - and to implement “state‑of‑the‑art” controls appropriate...

CISOs under NIS2 or DORA: the EU's Post-Quantum roadmap makes quantum a material, evolving governance risk you must track. It's not "deploy X by Y"—it's about auditable crypto agility and timelines supervisors will use (2030–2035). Read: postquantum.com/quantum-poli... #PQC #CyberSecurity

The EU Just Wrote Post-Quantum Cryptography (PQC) Into NIS2 On 20 January 2026, the European Commission published COM(2026) 13 final - a proposed directive amending NIS2 as part of a broader cybersecurity simplification package tied to the upcoming Cybersecurity...

EU takes a big step: COM(2026)13 would amend NIS2 to explicitly require Member States to include Post‑Quantum Cryptography transition policies in national cybersecurity strategies — turning PQC readiness from implied guidance into mandatory law.

Quantum Key Distribution (QKD): Why Countries Differ on Its Future Quantum Key Distribution (QKD) - a method of securing communications using quantum physics - has become a flashpoint...

QKD vs PQC: Countries are split. Some (e.g., China) build QKD networks, while the US/UK - and companies like Google - favor post-quantum cryptography. The NSA says it does not support QKD for national security. Read more: postquantum.com/post-quantum... #PostQuantum #QKD

The CRQC Quantum Capability Framework Detailed, end‑to‑end QC capability map for understanding what it will actually take to reach a cryptographically relevant quantum computer (CRQC)

Too many Q-Day predictions are “by vibes.” I’ve updated my CRQC Capability Framework - the evidence-based method used by national security analysts for years.

If you want to track Q-Day properly - QEC, connectivity, magic states, decoders - not hype: postquantum.com/post-quantum...

My blog PostQuantum.com just went over 1M unique visitors in 30 days. 37K in the last day.

The message is clear: Quantum security is no longer niche - and people are trying to cut through the hype, confusion, and pseudo-expert noise.

My point was - you were right. There is no law/regulation anywhere that mandates public notification of cyber incidents that impact lives, well-being, environment, or economy. Authorities often have to be notified. But never the impacted public in a way that they would be in case of a data breach.

2/2 …(in e.g. a manufacturing plant) were caused by a targeted cyber sabotage, the incident was recorded as an industrial accident and neither the company, law enforcement, national security agencies (not-UK)…wanted to deal with it. It’s a tough problem. So let’s pretend it doesn’t exist.
