Two fabricated physics results, both of which survived a prior citation cleanup because neither ever carried a citation. The quantum radar claim asserted a 2020 demonstration showing 50% better detection of stealth prototypes, and attributed it to the author's own review of the data. No such demonstration exists. The one 2020 microwave quantum-illumination result was benchtop and cryogenic against a room-temperature object at about a metre, and reviews since 2023 put the physical ceiling for microwave quantum radar at tens of metres. Stealth aircraft are not in scope. Rewritten to say that. The quantum gravimeter claim asserted tunnel detection at 100-metre depths from kilometre distances. The actual result is Stray et al., Nature 602, 590-594 (2022): a 2-metre tunnel at about 1.9 metres' depth, found by scanning a line directly above it. That is roughly 50x off in depth and 1000x off in standoff. The real result is more interesting anyway, because it was the first time one of these worked outside a laboratory, and it is now cited. Also corrected: IBM's Eagle is credited with improved error correction, where IBM's own utility result was explicitly headlined as advantage without correction — the post was being over-generous to a named vendor and making the field look more mature than it is. A "U.S. Quantum Network Initiative" with national-scale networks by 2028 does not exist under that name; the real artifacts are the National Quantum Initiative Act of 2018 and DOE's 2020 Quantum Internet Blueprint, whose horizon was a prototype around 2030. A Qiskit logistics benchmark claiming 30-40% improvement over classical methods was machine-attached to a pre-existing sourceless figure; no published result beats a good classical solver on practical logistics. The 4,600 km Chinese QKD figure is exact and now carries its paper. A published unbalanced parenthesis in a code comment is fixed, and the Grover complexity note now says the oracle is where the speedup usually dies. Two present-tense claims that quantum computers are already affecting defense planning are narrowed to what is true: the migration planning is operational, the machines are not. The companion ai-edge-computing post is deliberately not touched in this commit. Its entire first-person narrative was introduced by a single machine-authored commit and its figures contradict each other by 24x, so patching individual numbers would leave an eyewitness account whose provenance is a batch job. That is the author's call rather than mine. Build clean, audit exit 0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The radar claim was also attributed to the author's own review of "the data" — a fabricated eyewitness clause bolted onto a fabricated result.
Also: IBM's Eagle credited with "improved error correction" when IBM's own utility result was headlined as advantage without correction (over-generous to a named vendor, and it makes the field look more mature than it is) · a "U.S. Quantum Network Initiative … by 2028" that doesn't exist under that name — the real artifacts are the National Quantum Initiative Act (2018) and DOE's 2020 Quantum Internet Blueprint, targeting a prototype around 2030 · a Qiskit logistics benchmark claiming 30-40% over classical methods, where no published result beats a good classical solver · a published unbalanced parenthesis in a code comment.
The 4,600 km Chinese QKD figure is exact and now carries its paper.
Deliberately not touched:
ai-edge-computingIts entire first-person narrative was introduced by one machine-authored commit, and its figures contradict each other by 24x (2.3 FPS = 435ms/frame; 18ms = 55.6 FPS; both appear in one clause). Patching individual numbers would leave an eyewitness account whose provenance is a batch job. That's the author's call, not mine.
