Quantum Annealing’s Ideal Form Is the Gate Model in Disguise
A 2004 theorem says the idealized model behind quantum annealing and the gate model are one machine in disguise. Its proof freezes a computation at the bottom of an energy valley, and its fine print keeps annealers away from RSA.

FINMA Quantum Guidance Puts a Mid-2027 Date on Swiss PQC Roadmaps
Switzerland's financial regulator surveyed 60 institutions and found 72% with no quantum-safe measures. Its answer: board-level PQC strategies, roadmaps by mid-2027, and crypto-agility written into outsourcing contracts.

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.

Is Harvest Now, Decrypt Later (HNDL) Real? What I Can and Can’t Prove
No question comes up more often in my consulting and board sessions. For years I could only point to what spy agencies say. Here is the full answer: the written record, and the physics of collection.

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.

The ECB’s AI Cybersecurity Letter to Banks Is Also a Quantum Announcement
The euro area's banking supervisor gave 110 bank CEOs an October 31 deadline for AI cyber action plans, then used the final paragraph to start the quantum clock. Here is what the coming quantum letter will demand.

The Coming CRQC Blackout: Why the Papers Will Stop Before the Progress Does
The field ran three disclosure experiments in 2026: full openness, cryptographic secrecy, and silence. Only one is stable, and it ends our ability to track CRQC progress through published research.

Helium-3 Alternatives: Every Exit From the Shortage, Assessed
Ten engineering escape routes and one geopolitical wildcard for quantum computing's scarcest input, from breeding tritium on purpose to cooling qubits from inside the chip. I assess what each can deliver, what blocks it, and what would change the answer.

EU Funds QKD Certification Push With QUARTERNEXT
The EU is funding a four-year consortium to certify quantum key distribution for industrial use, even as its own cybersecurity agencies urge organizations to prioritize post-quantum cryptography. The tension is instructive.

Nobody Understands Quantum Mechanics. Everybody Uses It.
A board member accused me of selling a technology nobody understands. He was half right. The interpretation of quantum mechanics is unresolved. The mathematics has been tested to twelve decimal places and runs your phone.

Microsoft PQC Acceleration: What Was Announced
The company that said 2033 ten months ago now says 2029. With Google and Cloudflare already committed, three of the internet's most consequential infrastructure providers have converged on the same post-quantum deadline.

Post-Quantum OpenPGP Arrives: RFC 9980, the GnuPG Split, and the Signature Gap
The IETF has standardized ML-KEM, ML-DSA, and SLH-DSA for OpenPGP, with hybrid-only lattice cryptography and a v4 compatibility carve-out. The bigger story is the implementation split that decides whether any of it interoperates.
