Is Anything Unhackable? Reading Absolute Security Claims
No standard defines "unhackable", and no certification scheme awards it. Ask three questions instead: under which threat model, proven or tested by whom, and…
Every Exit From the Helium-3 Shortage
Seven ways out of the helium-3 shortage, graded on what each can deliver, what blocks it today, and the specific result that would change…
The Substitution Ladder: A Better Way to Read the Quantum Supply Chain
Grade every component by how many weeks of engineering a replacement costs. Three rungs, three procurement strategies, and one order of purchase that protects…
Cryogenic Infrastructure: The First Decision in a Superconducting Build
Three cryogenic constraints set the ceiling on any superconducting quantum build: fridge lead time, the helium-3 supply chain, and the I/O wiring wall. Sequence…
How to Choose a Quantum Control System
Control electronics decide whether a qubit chip ever computes. A selection sequence for engineers: latency budget, channel count, modality shortlist, and the supply constraint…
The Quantum OS and Orchestration Layer
Two of the five software layers in a quantum system come free with your hardware choices. Three do not, and two of those three…
Preparing a Facility for a Quantum Computer
A quantum computer is a building problem before it is a physics problem. What the site survey measures, which four sign-offs the schedule depends…
Quantum Hardware Costs More to Operate Than to Buy
The hardware quote is the smaller half of the number. Here is how the five-year cost of a quantum computer breaks down, and where…
CNSA 2.0 Explained: A Compliance Reading for GRC Teams
CNSA 2.0 is the one post-quantum directive written like a control rather than a goal: named algorithms, fixed parameter levels, dated procurement gates. A…
A Field Guide to Misleading Quantum Marketing
Quantum vocabulary moves procurement budgets, and marketing has noticed. The two shapes a bad claim takes, four questions that tell them apart, and what…
