Four Technologies That Decide Which Modality Scales
Qubit counts get the headlines. Control electronics, cryogenics, error correction hardware, and critical materials decide which architectures actually scale. A four-layer diagnostic.
Running a Sovereignty Stress Test That Can Fail
Most sovereignty tabletops end with the finding that the organisation would cope, because nobody defined coping first. A design guide for an exercise that…
Who Wins If Neutral Atoms Win: Mapping a Modality’s Supply Chain
Neutral-atom machines have no cryostat and no fabricated qubit chip. Almost everything hard about them is optical. A worked map of the bottlenecks, and…
Sovereign Optionality: What Quantum Independence Looks Like in a Contract
National strategies announce quantum sovereignty. Contracts decide it. The terms that determine whether a buyer can change supplier, jurisdiction, or architecture without restarting.
How to Tell a Quantum Chokepoint From an Inconvenience
Scarcity is the wrong first question. Five tests separate a dependency that stops your quantum program from one that only costs money and time,…
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…
A Field Guide to Quantum Geopolitics
National quantum programs reach most organisations as export licences, standards choices and supply chain constraints. Here is how to read them without the headline…
What Quantum Sovereignty Means, Layer by Layer
Quantum sovereignty is six separate control questions wearing one word. Here is what each layer means for a security architecture, and which ones you…
