Nuclear magnetic resonance spectroscopy and imaging at the ultimate sensitivity limit of single molecules or nuclear spins requires fundamentally new detection strategies. The strong coupling regime, when interaction between sensor sample dominates all other interactions, is one such strategy. In this classically forbidden completely unpolarized nuclei allowed, going beyond statistical fluctuations in magnetization. Here we realize an atomic (nitrogen–vacancy) to perform on four 29Si spins. We exploit field gradient created by diamond sensor, concert with compressed sensing, protocols, enabling individual be located Angstrom precision. achieved signal-to-noise ratio under ambient conditions allows spin within seconds. a powerful technique that can identify presence certain atoms their properties. Müller et al.now take concept its measuring near surface diamond.
