What’s Happening in Quantum — and What It Means
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 ...
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 rates is severe ...
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 ...
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 ...
G7 Tells Every Organization to Start PQC Migration – But the Procurement Signal Matters More Than the Headline
The G7 Cybersecurity Working Group's September 2026 call to action urges all organizations to begin PQC migration. The document is guidance, not regulation, but its procurement and supply chain language carries real consequences for enterprises and their vendors ...
AIX Global Innovations Claims to Have Solved All Six Millennium Prize Problems. Its Own Lean Audit Says Otherwise.
AIX Global Innovations says its proprietary quantum stack solved all six remaining Clay Millennium Problems. The Lean package it released does not show six closed proofs. Its own audit exposes the missing premises ...
IBM Connected Two Quantum Cryostats. The Three Numbers That Matter Were Not in the Press Release
IBM has connected and cooled two modular cryogenic cells. Beyond the press release, its specification sheet and briefing coverage disclose 30 kW per module, 23 mK with a simulated payload, and 99.3 percent interconnect fidelity. The design also requires warming the connected system for cryogenic ...
Sweden Publishes Its First National Quantum Strategy
Stockholm has published the document its research community asked for two years ago. The goals run a decade. The programme that built the country's quantum research base is funded for four more years. The strategy is silent on what follows ...
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 ...
China Set a 420 km Quantum-Memory Entanglement Record. The Two Ends Were in One Lab.
Pan Jianwei's group heralded entanglement between two rubidium memories across 420 kilometers of fiber, published in Physical Review Letters on August 11. The concurrence at that distance sits about 2.1 times its own quoted uncertainty above zero ...
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 ...
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 ...
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 ...
