What Early Quantum Buyers Are Actually Paying For
Current quantum computers can't beat a laptop on real work, yet governments and enterprises keep buying them. Which justifications hold up in a business…
China’s Quantum Talent Machine, and What It Couldn’t Buy
Two decades of state recruitment gave China a world-leading quantum program and left it short where it matters most. The workforce lesson transfers to…
How to Read China’s Quantum Supply Chain
China went from zero domestic dilution refrigerator makers in 2021 to roughly ten. Here is how to read a supply chain claim like that…
How to Read China’s Quantum Computing Hardware Record
Two laboratories on Earth have published below-threshold quantum error correction, and one of them is in Hefei. A working method for separating demonstrated capability…
Quantum Sovereignty and Geopolitics: The Short Version
Export controls, investment screening, and diverging PQC standards have turned quantum sovereignty into a procurement question. The short version, for architects and buyers.
When Geopolitics Becomes Architecture
Export controls now trigger on qubit count and gate error rate together. Sovereignty has moved out of the policy brief and into the bill…
Four Questions That Map a Quantum Supply Chain
Vendor roadmaps name qubit counts, not the suppliers whose capacity sets delivery dates. Four questions that surface concentration, jurisdiction, and shared dependency.
Who Wins If Silicon Spin Wins
Silicon spin qubits borrow most of their supply chain from the semiconductor industry. We work through who supplies each layer, where the chokepoints are,…
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…
