Evaluating a Quantum Company: The Claims
A quantum performance claim is scoreable when five things are present: the unit, the population, the conditions, the baseline, and the witness. Here is…
Six Control Points in a Rented Quantum Computer
Most organisations will rent quantum access, not own it. Six control points decide how much sovereignty survives the contract, and each one is negotiable.
What Quantum Systems Integration Actually Involves
Open architecture turned the quantum computer into a set of parts. Someone still has to assemble them and connect the result to the infrastructure…
Q-Day Is a Confidence Crisis, Not an Outage
The morning a quantum computer factors an RSA-2048 key, nothing goes dark. What ends is the presumption of safety, and the questions start within…
The Four Axes Where National PQC Requirements Diverge
Approved algorithm lists are the first of four axes on which national post-quantum requirements diverge. The other three are harder to abstract away.
Trust Now, Forge Later: The Signature Half of the Migration
Harvest Now, Decrypt Later sets its clock by data retention. The signature side of the quantum problem sets its clock by deployment lifetime, and…
Quantum Readiness Is Not Only a Vendor Problem
Suppliers will ship post-quantum algorithms. The cryptographic inventory, the risk decisions and the contract terms are work no supplier can do on your behalf.
Who Really Wins If Photonics Wins
The photonic bet is a manufacturing bet. Which means the winners, if it pays off, are decided layer by layer, and most of them…
Who Really Wins If Trapped Ions Win
Trapped-ion quantum computing has no single chokepoint like the dilution refrigerator. It has a contested one, and most of it sits in Europe while…
Who Wins If Superconducting Wins
A refrigerator company just signed a decade-long contract for helium mined on the Moon. Here is what the superconducting supply chain looks like layer…
