Abstract

We study decoherence of a single nitrogen-vacancy (NV) center induced by the 13C nuclear spin bath of diamond. By comparing Hahn-Echo experiments on single and double-quantum transitions of the NV triplet ground state we demonstrate that this bath can be tuned into two different regimes. At low magnetic fields, the nuclei behave as a quantum bath which causes decoherence by entangling with the NV central spin. At high magnetic fields, the bath behaves as a source of classical magnetic field noise, which creates decoherence by imprinting a random phase on the NV central spin.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For the PCC-N-V system, the optical transition dipole moment d∼4×10^-30 C·m and typical transition frequency ω0∼2.9 PHz lead to β∼1 GHz.

    “For the relevant experimental parameters, the optical transition dipole moment and the typical transition frequency of the N-V center are observed to be d ∼ 4 × 10 -30 C · m [31, 32] and ω 0 ∼ 2 . 9PHz [33], which lead to β ∼ 1GHz .”

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.
