Guarding the CBOM: The Most Sensitive Document Your Security Program Produces
Cryptographic discovery finds weaknesses that matter today, not only after a quantum computer. The resulting inventory ranks them, stays useful to attackers for years, and almost nobody has said to guard it.

The Merchant QPU Market – Who Will Actually Sell You a Quantum Processor
Strip away cloud access and turnkey machines and the number of companies that will sell a quantum processor for third-party integration drops to six. An audit of the merchant market, with prices, specs, and the gaps.

The Ethereum Foundation Spent Eight Years on a Hash Its Roadmap No Longer Needs
Binary-field proof systems made standard hashes cheap enough to prove that Ethereum's exotic one lost its reason to exist. Nobody broke it. An eight-year research bet was retired in a single post.

The White House Authorized Private Hack-Back. I Spent 11 Years Arguing Against It.
The August 12 memorandum puts vetted American firms inside a federal offensive pipeline. Work through the text and the party that keeps getting hit is the United States.

Google Cloud Put Dates on Its PQC Migration. Signatures Trail Confidentiality by a Year.
Google Cloud has attached target years to 19 service-level roadmap entries running through 2029. Store-now-decrypt-later mitigation is due in 2027, signatures and key-management foundations in 2028.

I Set Five Tests for Silicon Spin in March. One of Them Was Too Weak.
Two cleared, one partial, one open, and one that HRL passed as written while leaving the thing it was meant to measure exactly where it was in March.

Six Teams Shipped the Same ZK Verifier Bug. Quantum Doesn’t Get a Patch.
Zcash closed a 3.66 million ZEC pool to new deposits after a soundness bug surfaced in a Shielded Labs audit. A quantum verifier migration is harder, and no regulator can schedule the fork.

When Two Cryptographers Independently Confirm a Break, Ask Which Model They Used
Two proofs of the same result landed three hours apart from the same model, and Simon's DCP claim is now being taken apart by humans and models working together. Separate names no longer establish separate failure modes.

A New Classic McEliece Distinguisher Undercuts Generic Decoding. It Is Not a Break.
No security claim has fallen and the scheme is not broken. What fell is the quantitative argument that made structural attacks easy to set aside, because one now costs less than generic decoding on every NIST parameter set.

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.
