Claims

C1strongest claim

We demonstrate a technique that allows for both optical polarization and readout of large ensembles of ~10^{16} polarized nuclear spins... realize a nuclear-spin-dependent fluorescence contrast exceeding 0.5% peak-to-peak. We observe nuclear spin dephasing times T2*~2 ms that only modestly improve with homonuclear dipolar decoupling, indicating that they are limited by the longitudinal spin relaxation of nearby NV electron spins.

C2weakest assumption

The assumption that the observed fluorescence contrast arises specifically from remote 13C nuclear spins via efficient bidirectional Landau-Zener transfer and that T2* is limited by NV relaxation rather than other unaccounted mechanisms or sample variations.

C3one line summary

A microwave-sweep technique using Landau-Zener transitions transfers polarization between NV electron spins and remote 13C nuclei, enabling optically detected NMR with >0.5% contrast and ~2 ms T2* in natural-abundance diamond.
