Alice & Bob Estimates 22,593 Qubits Could Break RSA-2048 in Three Days, but Nobody Can Build Those Qubits Yet
Alice & Bob's new estimate puts RSA-2048 at 22,593 cat qubits and 3.14 days, small and fast at once. Here is what that rests on, and a reality check for the headlines it will produce.

NIST Finalizes Its Post-Quantum Transition Plan, Deprecating RSA and ECC at All Approved Key Sizes After 2030
In the final version of its post-quantum transition report, NIST added a deprecation step after 2030 for P-256, RSA-3072 and other 128-bit classical parameters. NIST also confirmed that hybrid key exchange can be FIPS 140-validated after 2035.

Israel Innovation Authority Says the Country’s Quantum Edge Is Software and Control, on the Day Intel Announced a Deal to Buy Classiq
Israel's quantum sector grew from about five companies in 2019 to more than 20, with over $1 billion in private funding. A new national review explains how, but its budget and funding-ratio figures need qualifying.

Intel Agrees to Buy Quantum Software Maker Classiq Before It Has a Quantum Computer to Sell
Intel has agreed to buy Tel Aviv quantum software company Classiq, reportedly for about $2.3 billion, while its own spin-qubit hardware is still in research. Intel now has to show that a chipmaker can keep a quantum compiler neutral.

Iceberg Quantum Estimates 72,000 Qubits Could Break RSA-2048 in 3.7 Days but Hasn’t Published the Circuits or the Decoder
In Pinnacle 1.2, Iceberg Quantum reports direct simulations of its logical error rates and cuts its estimated spacetime cost of factoring RSA-2048 about tenfold. The circuits and the Crevasse decoder behind the numbers remain unpublished.

Sectigo Reports 38% Have Fully Assessed Their Quantum Exposure, but Only 4% Say Their Certificate Management Is Fully Automated
In its 2026 survey of 500 IT and security leaders, Sectigo reports more quantum assessments and fuller certificate inventories than in 2025. Reading its appendix alongside Chrome's post-quantum certificate plans, I see certificate automation as the work due first.

Key Ceremonies: What They Are, What Good Looks Like, and What PQC Changes
A key ceremony produces the main evidence that a CA key was generated correctly. What the rules require and miss, what a good ceremony looks like, the skills it needs, and what PQC changes.

eMudhra CA Keys: A Q-Day Rehearsal at the Scale of One CA
A ceremony error left eight eMudhra intermediate CA keys computable from their certificates for 17 months. Chrome and Firefox blocked them within hours. Linux, runtimes and devices could take years, and a CRQC would expose every classical CA key.

Quantinuum Reports Record Error Suppression on Helios, at About a Fifth of a Second per Correction Round
On Helios, Quantinuum held a distance-7 color-code logical qubit at five errors per million correction rounds. Errors fell about twelvefold per code-size step on average. Each round lasted close to 200,000 times as long as one on Google's Willow.

IBM’s AI Agents Cut a Quantum Decoder’s Estimated Latency 52-Fold for $26 and 204-Fold for $299
IBM let AI coding agents rework the hardware design of its Relay-BP quantum decoder, at an estimated $26 in inference with open-weight models. By the synthesis tool's estimates, even the best design is far slower than IBM's hand-written decoder.

MITRE Rated Eight Enterprise Technologies on Post-Quantum Readiness. Key Exchange Is in General Release in Five, Signatures in Two.
In a July review of public evidence, MITRE found no enterprise technology category with FIPS-validated post-quantum support and no post-quantum hardware TPM on sale. What that means for agencies planning toward 2030 and 2031.
