A $9.4 Billion Day for IBM Quantum Fusion Chemistry
IBM gained close to ten billion dollars in market value the day it announced quantum computations of fusion blanket chemistry. The paper's own resource tables show which half of the workflow actually fell short.

Five Tests for Genuine Quantum Advantage, From Huang, Choi, McClean, and Preskill
Four leading theorists publish a framework separating genuine quantum advantages from illusions, plus a proof that some advantages cannot be predicted classically. The claim that fares best under their five tests is Shor's algorithm, the one that breaks RSA.

Reinforcement Learning Quantum Error Correction: Google’s Willow Learns to Calibrate Itself
Google's agent steers more than 1,000 control parameters using nothing but error-detection statistics, holding surface codes steady against drift and squeezing 20% more performance from an exhaustively calibrated processor. The catch sits in the simulations.

Diraq Eight-Qubit Foundry Silicon Array
Diraq and imec tuned and coherently ran eight foundry-fabricated silicon spin qubits on one chip. Coherence matched the two-qubit devices; entangling gates worked in one of four pairs. My read on the CMOS scaling thesis.

IonQ Demonstrates qLDPC Breakeven on Trapped Ions — and the Flexibility Argument Just Got Harder to Ignore
IonQ's 40-ion trapped-ion device runs nine different error-correcting codes with zero hardware changes and hits breakeven on qLDPC codes — beating the only superconducting comparison by up to 9×. The real story is what this means for the qubit-efficient architectures the field is betting on.

Bernstein Demonstrates ML-DSA Key Recovery in Under One Second, Argues Solo Deployment Damages Security
Daniel J. Bernstein provides the first working attack demos against ML-DSA implementation bugs, recovers equivalent secret keys in under one second, and builds a quantitative case that solo ML-DSA deployment damages security compared to hybrid Ed25519+ML-DSA.

OQC Raises £260M in Europe’s Largest Private Quantum Round — Where the Money Actually Goes
Europe's largest private quantum round lands at £260M, with 38% from the British Business Bank. The money is earmarked for OQC's TITAN system, but the gap between 32 qubits today and 200 logical qubits by 2028 demands closer examination.

Microsoft’s Majorana 2 Chip Achieves 20-Second Parity Lifetime — But the Topological Qubit Debate Rages On
Microsoft's second topological quantum chip achieves a 1,000-fold improvement in parity lifetime by swapping aluminum for lead. The engineering progress is real. Whether these are topological qubits at all remains fiercely contested.

Google’s Secret Quantum Circuits for Breaking ECC Reproduced and Improved in Two Months
A French researcher independently matched Google's secret quantum circuits for breaking elliptic curve cryptography, then improved the gate count. Google's Craig Gidney says the zero-knowledge approach failed and open publication should resume.

IBM’s Concatenated Gross Code Reaches the Teraquop Regime
IBM's QEC team packages 11 logical qubits into a single high-dimensional qudit and wraps the gross code in quantum Reed-Solomon algebra. The result: a fault-tolerant memory that reaches the teraquop regime the gross code couldn't previously access.
