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…
What It Takes to Build a Quantum Computer
A quantum computer is assembled by six engineering trades, only one of which is quantum physics. Here is what each of them does, and…
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…
Following a Hybrid Job Through a Quantum-HPC Stack
A QPU next to a supercomputer is a demonstration. A QPU inside the job queue is a resource. Here is what sits between the…
Who Should Own Post-Quantum Migration
Post-quantum migration programs stall on ownership, not technology. Four tests for naming the accountable executive, and the mandate, budget, and authority the role needs…
What Crypto Holders and Builders Should Do Now
No quantum computer can break blockchain signatures today. The published migration deadlines still bind. Here is what to do without waiting for anyone.
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…
What Bitcoin’s Post-Quantum Migration Actually Requires
A new output type, a signature algorithm choice, a fee-market renegotiation, and a multi-year UTXO sunset. The engineering pieces of Bitcoin's PQC migration, and…
Ethereum’s Five Quantum Vulnerabilities and Who Owns Each Fix
One network, three cryptographic primitives, five layers, five different sets of owners. Ethereum as a worked example in reading a cryptographic inventory.
How to Tell a Real Quantum Application From a Marketed One
Five industries have published evidence for quantum advantage. Roughly twenty do not. Three questions, asked in order, separate the two lists before any money…
