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…
Why Countries Disagree About QKD
The NSA will not certify QKD for national security use. China runs a 4,600 km quantum network. Both are current positions. Here is the…
Rethinking the CBOM
Complete cryptographic inventory is a mirage. A Minimum Viable CBOM maps trust boundaries first, records what you don't know, and produces migration decisions instead…
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…
Evaluating a Quantum Company: The Technology
Qubit count is the easiest number to quote and the least informative. A working guide to the metrics, modalities, and manufacturing questions behind a…
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.
Access, Not Ownership: How Governments Screen Quantum Deals
Investment screening in quantum no longer asks who owns a company. It asks who can reach the technology. A field guide to the five…
Evaluating a Quantum Company: The Business
Technology diligence tells you whether the machine can be built. Commercial diligence tells you whether the company will still be there when it is.…
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,…
