Abstract

Light emission stemming from V impurities in $4H$-SiC is recorded at 1.28 and 1.33 $\ensuremath{\mu}$m, in the telecommunication $O$ band, which gives hope for the creation of efficient single-photon sources in existing telecommunication networks, ultimately paving the way for secure long-range quantum communication networks. Combined with the available electronic and nuclear degrees of freedom, vanadium presents all of the required ingredients for a highly efficient spin-photon interface. These V centers are reminiscent of the Mo defect in SiC and the Si-$V$ complex in diamond, but work at practical wavelengths for telecommunication.

  • Emerging SiC color centers, such as the NV and the vanadium center, are currently explored in the range 1300-1550 nm.

    “While Si vacancy and divacancy in 4H-SiC provide longer operating wavelengths than diamond defects and QDs, emerging SiC color centers, such as the NV [128, 129] and the vanadium center [130], are currently explored in the range 1300-1550 nm.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
