Abstract

fetched live from OpenAlex

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(2i/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.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
