Two QFT Records in Four Months. Neither Gets You Closer to Breaking RSA.
Two compilation teams claimed the largest quantum Fourier transform ever run, four months apart, on the same IBM chip. Their circuits and metrics are not comparable, and the gate counts explain why.

AI Governance Is Repeating Cybersecurity’s Mistakes
Cybersecurity never eliminated conflicts over testing, disclosure, and oversight. It built mechanisms to expose and manage them. July's AI evaluation failures show which of those mechanisms frontier labs still lack.

AI Hacking Theater and the Crypto-Agility Wake-Up Call
OpenAI and Anthropic spent two weeks one-upping each other's AI hacking disclosures. Buried beneath the competitive theater are three developments CISOs can no longer ignore, and the defense for all three is the same.

AI Can Hack Everything? Do the Math First
Everyone is selling protection from AI hackers. Almost nobody is asking whether AI attacks can actually scale, or whether the answer was sitting in their security budget the whole time.

Why the OpenAI Breach Matters for Quantum Strategy
Everyone is covering the OpenAI/Hugging Face breach as an AI scare. The real lesson is in the forensics: US models blocked defenders, a Chinese model did the job, and the same flawed control logic governs quantum.

Why Europe Is Industrialising CV-QKD
QUARTERNEXT places CV-QKD at the centre of one European industrialisation track. EuroQCI remains deliberately multi-protocol. The real story is how telecom integration, certification, and supply-chain control shape the portfolio.

How Much Can AI Help With PQC Migration?
AI is already part of PQC migration, and it helps. But the claim that frontier models compress enterprise timelines from 15 years to four confuses which part of the program AI accelerates and which part it cannot touch.

You Cannot Detect Harvest Now, Decrypt Later (HNDL)
Vendors are beginning to sell HNDL detection. Boards are asking for proof of HNDL targeting. Neither is possible. Passive collection leaves no observable event inside your network. The defense is encryption, not detection.

Is Harvest Now, Decrypt Later (HNDL) Real? What I Can and Can’t Prove
No question comes up more often in my consulting and board sessions. For years I could only point to what spy agencies say. Here is the full answer: the written record, and the physics of collection.

The Coming CRQC Blackout: Why the Papers Will Stop Before the Progress Does
The field ran three disclosure experiments in 2026: full openness, cryptographic secrecy, and silence. Only one is stable, and it ends our ability to track CRQC progress through published research.

The Shannon Hustle: How Vendors Abuse Perfect Secrecy to Sell You Less Than You Think
Vendors drop "Shannon" into pitch decks to imply information-theoretic security. The math says otherwise. A five-question framework for evaluating any claim of perfect secrecy with practical key sizes.

US Federal PQC Mandate After June 2026: Complete Guide
June 2026 transformed US PQC policy from planning guidance into enforceable mandates. This is the complete picture: what applies to whom, by when, and under which authority.

Why the Quantum Attack on ECC Keeps Getting Cheaper, and Where It Stops
An open competition has driven the logical qubits for one secp256k1 point addition into the high 1,100s. The arithmetic says how much further circuit tricks can go, and exactly where they stop.
