Abstract
Telecom-wavelength single photons are the leading carriers of quantum information for practical photonic quantum technologies, and there has been significant progress in developing compatible components like detectors and single-photon sources. However, an on-chip, broadband quantum memory for storage and reemission of single telecom photons---indispensable for future quantum repeaters---has been lacking. The authors demonstrate a light-matter interface for quantum storage of 1532-nm photons: a cryogenically cooled lithium niobate crystal waveguide. The memory hinges on a broadband atomic frequency comb created by persistent spectral hole burning through long-lived superhyperfine levels.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
