Abstract
Let n be a positive integer divisible by 8.The Clifford-cyclotomic gate set G n consists of the Clifford gates, together with a z-rotation of order n.It is easy to show that, if a circuit over G n represents a unitary matrix U, then the entries of U must lie in R n , the smallest subring of C containing 1/2 and exp(2πi/n).The converse implication, that every unitary U with entries in R n can be represented by a circuit over G n , is harder to show, but it was recently proved to be true when n = 2 k .In that case, k -2 ancillas suffice to synthesize a circuit for U, which is known to be minimal for k = 3, but not for larger values of k.In the present paper, we make two contributions to the theory of Clifford-cyclotomic circuits.Firstly, we improve the existing synthesis algorithm by showing that, when n = 2 k and k ≥ 4, only k -3 ancillas are needed to synthesize a circuit for U, which is minimal for k = 4. Secondly, we extend the existing synthesis algorithm to the case of n = 3 • 2 k with k ≥ 3.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
