AI Security
Alignment Is Whether AI Wants to Kill Us. Cybersecurity Is Whether We Let It.
The people who build frontier AI ask how a model could ever take power. The July 2026 intrusions answered the first step and half of the second. The rest run through controls organisations already own and already fail at.

IBM’s Spacetime PEC Cuts Error-Mitigation Sampling Overhead 63× – But the Exponential Wall Remains
IBM researchers combined probabilistic error cancellation with post-selected error detection, reducing sampling overhead by up to 63× on a 49-qubit subset of IBM's 156-qubit Heron processor. The result extends near-term error mitigation but does not eliminate its exponential cost.

Altera and Riverlane Validate QECi on Agilex FPGAs – and the Day After, Qblox Closes the Real-Time QEC Loop at 6.9 µs
Riverlane validated QECi on Altera Agilex 7 FPGAs on September 10, and Qblox closed a real-time QEC loop over it the next day using emulated qubit data. QECi is the first purpose-built, open-source, multi-vendor QEC interface stack with closed-loop results.

Cloudflare’s 1.1.1.1 Now Validates Post-Quantum DNSSEC Signatures – And Shows Why PQC Migration Is a Systems Problem
Cloudflare enabled ML-DSA-44 DNSSEC validation on its 1.1.1.1 resolver. No other major public resolver has announced equivalent support. The move exposes transport, downgrade, and chain-of-trust challenges that will define PQC migration beyond TLS.

Xanadu and AMD’s Backline Opens a Third Front in the Quantum Control Stack Race
Xanadu and AMD released Backline, an open-source platform that connects quantum control hardware to standard AMD CPUs with sub-3µs round-trip latency. The announcement adds a third architectural option to a control-stack race that includes NVIDIA's NVQLink and Riverlane's QECi.

Google’s Multiverse Claim Was a Serious Argument Attached to the Wrong Experiment
Google attached a serious interpretation of quantum mechanics to a benchmark every standard interpretation predicted, and whose headline run was never directly verified. Ten months later the same lab kept the interference and left the metaphysics out.

Quantum Capability Has Doubled Every One to Two Years. Sandia Says the Early-2030s Roadmaps Need Four Times That.
A Sandia-led team ran identical circuits on Google, IBM and Quantinuum processors, then on a fault-tolerant architecture built from logical qubits. The encoded version reached 2.7% of the raw machine's score.

Chip-Based QKD Has a Glow Problem: VOA Luminescence Creates a Side Channel That Standard Security Analyses Miss
A peer-reviewed study finds that variable optical attenuators in integrated QKD chips emit unintended light near 1107 nm. The emission creates a wavelength-resolved side channel that standard BB84 security analyses do not account for, and the modeled impact on key…

Washington Took Its Quantum Stakes Up Front and Tied the Cash to Milestones
Commerce finalized equity-linked CHIPS awards with D-Wave, Rigetti, Quantinuum and PsiQuantum on September 8. The public filings show shares issued for each full award at signing, about half the money available up front, and the rest tied to milestones.

Quantinuum’s Helix Demonstrates How a Compact Error-Correcting Code Can Compute
Quantinuum's Helix architecture demonstrates logical memory, Clifford computation and an inter-code interface on Helios – all without postselection. The gap between these components and sustained universal computation defines what comes next.

Fujitsu Built a Diamond-Spin Quantum Prototype. The Numbers That Would Prove It Scales Are Missing.
Fujitsu says it has built the first diamond-spin quantum computer prototype to integrate a tin-vacancy center with an on-chip photonic circuit. The fabrication is real. The scalability metrics that would validate the modular architecture are not yet published.

Altera Ships ML-DSA Secure Boot on Agilex FPGAs – PQC Reaches the Silicon Root of Trust
Altera began shipping ML-DSA secure boot on its Agilex 3 and Agilex 5 FPGAs on September 8, 2026 – the first general-purpose FPGA family with post-quantum firmware authentication as a production feature, not a roadmap item.

IonQ Compiles Shor’s Attack on secp256k1 Down to 19,397 Ions and 26 Days per Attempt
IonQ has compiled a full ECDLP-256 attack to a trapped-ion design that does not exist, charging every Clifford, measurement and ion transport. The accounting is the most detailed I have seen. The error rates, cycle time and machine are assumptions.

Copenhagen’s Quantum Foundry Plans a 5,300-Square-Meter Chip Fab – But What Will It Actually Build?
Quantum Foundry Copenhagen, owned by the Novo Nordisk Foundation, plans a 5,300-square-meter quantum chip fab for 2027. It lists superconducting, semiconducting and photonic components but has not named a customer or said which it will make at scale.

Everything Called a Decoder in Quantum
A syndrome decoder has to keep pace with a microsecond syndrome stream. A syndrome decoding problem has to stay infeasible forever. Same two words, opposite requirements, and coverage that routinely cannot tell them apart.
