Abstract

fetched live from OpenAlex

The silicon T center's narrow, telecommunications-band optical emission, long spin coherence, and direct photonic integration have spurred interest in this emitter as a spin-photon interface for distributed quantum computing and networking. However, key parameters of the T center's spin-selective optical transitions remain undetermined or ambiguous in the literature. In this paper, we present a Hamiltonian of the T center TX state and determine key parameters of the optical transition from ${\mathrm{T}}_{0}$ to ${\mathrm{TX}}_{0}$ from a combined analysis of published results, density functional theory, and new spectroscopy. We resolve ambiguous values of the internal defect potential in the literature, and we present the first measurements of electrically tuned T center emission. As a result, we provide a model of the T center's optical and spin properties under strain, electric, and magnetic fields that can be utilized for realizing quantum technologies.

Not 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.
