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.
Where Telecom Operators Should Start
The algorithms are settled. What stops most carriers is that nobody can yet read a cryptographic inventory and say which findings matter first.
What Actually Binds You in the US Post-Quantum Rulebook
Statutes, executive orders, OMB memoranda, federal standards, acquisition rules and standard of care all bind differently. A field guide to sorting them, with three…
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,…
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 organization 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…
