High‐Resolution Single Photon Level Storage of Telecom Light Based on Thin Film Lithium Niobate Photonics
Bibliographic record
Abstract
Abstract This study presents an experimental analysis of high‐resolution single photon buffers based on low‐loss thin film lithium niobate (TFLN) photonic devices operating at room temperature. While dynamically controlling writing and reading operations within picosecond timescales poses a challenge, the devices are capable of resolving 102.8 4.6 ps time step with ‐0.89 dB loss per round‐trip and 197.7 6.6 ps time steps with ‐1.29 dB loss per round‐trip, respectively. These results imply that the devices are at the cutting edge of on‐chip technology, performing in the current state of the art at the single photon level. Both of the single photon buffers do not introduce any detrimental effects and provide a high signal‐to‐noise ratio (SNR). The room‐temperature, low‐loss, and voltage‐controlled TFLN buffers combine scalable architecture with relatively high buffering capacity in the sub‐nanosecond regime and are expected to unlock many novel photonics applications such as temporally multiplexed single photon sources.

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.
