Quantum’s Wild Week The week quantum research smashed timelines and regulators and industry organizations yelled “Move faster!”

A single day with 4 breakthrough quantum tech developments - each with the potential to accelerate the arrival of Q-Day.

That’s exactly what happened on Sept 24–25.
I break it all down in the first issue of The Quantum Observer: quantumobserver.com/p/quantums-w...

#QuantumComputing #PQC #QDay

Quantum’s Wild Week The week quantum research smashed timelines and regulators and industry organizations yelled “Move faster!”

What a week for quantum tech! Qubits leaping ahead of schedule, Caltech scaling to 6,100, HSBC finding real quantum advantage, NIST issuing new PQC guidance - and more.

I unpack it all in the first edition of The Quantum Observer: quantumobserver.com/p/quantums-w...

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.

Ciaran, well said! I spent 20 years of my career focused on these kind of attacks on cyber-physical systems. I coined the term “cyber-kinetic attacks” in the 1990s for these kind of cyber attacks that impact lives, well-being and the environment. Even when my teams conclusively proved that deaths…

Quantum-safe upgrades aren’t just for your encryption appliances – they’re for every system that touches crypto. This article drives home that point: nearly every enterprise system uses cryptography so almost everything will need some update for the quantum era postquantum.com/post-quantum...

TL;DR from this deep-dive: transparency is security. A CBOM brings cryptography out of the shadows. Expect CBOMs to become as routine as SBOMs in audits. It’s a bit more work now for a lot more peace of mind later. #PQC #CryptoAgility postquantum.com/post-quantum...

Q-Day Revisited - RSA-2048 Broken by 2030: Detailed Analysis It’s time to mark a controversial date on the calendar: 2030 is the year RSA-2048 will be broken by a quantum computer - or the Q-Day.

Why 2030 for Q-Day? 3 pieces of recent news: IBM plans ~200 logical qubits by 2029, Gidney’s 2025 paper showed ~1300 logical qubits running 1 week could factor RSA-2048, and Oxford set a record for low error rates. Put together, that makes a 2030 plausible. postquantum.com/post-quantum...

CBOM (Cryptography Bill of Materials) is the new buzzword. Think SBOM but for encryption. To migrate to #PQC, you first need a map of every place cryptography lives in your org. This article shows how various tools help assemble that map. #CryptoAgility postquantum.com/post-quantum...

No, migrating to #PQC isn’t a “one-click” software patch. In reality, it’s a years-long effort: you need to map all your crypto usage, replace algorithms across apps, devices, and protocols, and do tons of testing. There’s no “easy” button to become #QuantumResilient. postquantum.com/post-quantum...

Bottom line: has anyone come close to cracking RSA-2048 with quantum? Not really – it’s still a theoretical threat. The “48-bit factoring” hype taught us that claims of “RSA broken” will surface periodically and we need to critically evaluate them. postquantum.com/post-quantum...

Government of Canada Launches Post-Quantum Cryptography (PQC) Migration Roadmap On June 23, 2025 Canada has issued a new roadmap for migrating the Government of Canada’s IT systems to post-quantum cryptography (PQC).

Canada’s PQC roadmap means business: by 2026 every federal agency must inventory its crypto use and designate a lead for the transition. Annual progress reports will be mandated. Essentially, they’re baking #QuantumReadiness accountability into government operations. postquantum.com/industry-new...

Why do we suddenly need CBOMs? Because you can’t swap in quantum-safe algorithms if you don’t know what you have. Governments are now mandating agencies to inventory their cryptography. CBOMs make that practical by formalizing the process. This article explains... postquantum.com/post-quantum...
