Post-Quantum, PQC, Quantum Security
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.

A Peer-Reviewed CRYPTO 2026 Paper Just Gave ML-KEM’s Foundation a New Quantum Target
Wen and Zheng prove Module-LWE quantum-polynomially equivalent to a structured dihedral problem and reduce it to EDCP. The result maps ML-KEM's mathematical foundation into territory three research groups are actively probing with quantum algorithms.

Daniel Simon Claims a Polynomial-Time Quantum Algorithm for Lattice Problems. And a CRYPTO 2026 Paper Connects It to ML-KEM
Daniel Simon has posted a preliminary polynomial-time algorithm for the Dihedral Coset Problem, and a peer-reviewed CRYPTO 2026 result supplies the Module-LWE link. Neither one breaks ML-KEM. Together they change the risk conversation.

Qarakal’s Pangaea Architecture Shrinks the Routing Region Tenfold, Not the Machine
The preprint behind the announcement is careful work with a real result. The result is a saving of under two times on a 50-logical-qubit machine, and the tenfold figure on the wire counts something narrower.

D-Wave’s First Gate-Model Nature Paper: Why Error Structure Can Beat Error Rate
D-Wave's first gate-model Nature paper demonstrates a dual-rail erasure qubit entangling gate that preserves the noise hierarchy needed for efficient error correction. Simplified surface-code simulations show why structured errors can offset a higher aggregate error rate.

Quantum Careers in 2026 (No PhD Required)
An updated map of quantum careers: what each role involves day to day, who hires for it, what employers screen for, and how to judge whether a specialization will still exist in ten years.

Allianz Quantum Risk Report Gets the Capital Thesis Right and the Cryptanalysis Wrong
Allianz Research published a technically serious quantum risk assessment for finance. Its capital-flow analysis is unusually effective. Its cryptanalytic chart and threat model need corrections that matter for anyone using it to plan.

First External Operators Apply to Chrome’s Post-Quantum Certificate Test Program
TrustAsia filed the first known CA application for Chrome's Merkle Tree Certificate test root store. The filing implements two recently standardized mechanisms from the IETF PLANTS draft, adding concrete evidence that post-quantum web PKI infrastructure is moving from draft to…

Mitten Codes Put 195 Logical Qubits in 975 Physical Qubits, Complete with Fault-Tolerant Processor Design
Caltech and Oratomic introduce mitten codes, a family of 20%-rate qLDPC processor codes. In simulations, a [[540, 108, 18]] block produced two failures across 15 billion surgery quops at 0.1% physical error rate, consistent with an expected processing capacity of…

DARPA’s Most Rigorous Quantum Evaluation Is Led by Its Least Proven Contenders
Neither Stage C company has publicly demonstrated a logical qubit on the architecture DARPA is evaluating. One may not have demonstrated a physical qubit. That outcome tells you more about the program's design than about the technology.

Every Quantum Vendor Measures Progress Differently. That’s the Point.
Quantum vendors report different measures of scale, fidelity, throughput, and logical performance. Each number may be valid, but together they do not form a common scoreboard. Here is why that matters.

HKMA Gives Hong Kong Banks a 2.3 Out of 10 on Quantum Readiness, Targets Full Migration by 2030
HKMA's first Quantum Preparedness Index scores Hong Kong's banking sector PQC readiness at 2.3 out of 10. Most respondents remain at an early stage, while the regulator targets full sectoral readiness by 2030.

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.

I Spent a Year Writing About Europe’s Quantum Failures. Now I’m Moving My Company There.
I've spent the past year documenting Europe's quantum commercialization gap. Now I'm moving Applied Quantum's headquarters from Singapore to the EU. The contradiction is only apparent.

87% of Organizations Are Pursuing PQC. Only 7% Have Deployed It.
DigiCert's second annual PQC survey finds at-scale certificate deployment barely moved in a year. The barrier profile now points to execution, not awareness, and that tells us more than the headline number.
