Quantum systems that consist of solid-state electronic spins can be sensitive
detectors of nuclear magnetic resonance (NMR) signals, particularly from very small
samples. For example, nitrogen–vacancy centres in diamond have been used
to record NMR signals from nanometre-scale samples, with
sensitivity sufficient to detect the magnetic field produced by a single
protein. However, the best reported spectral resolution for NMR
of molecules using nitrogen–vacancy centres is about 100 hertz. This is insufficient to resolve the key spectral identifiers of
molecular structure that are critical to NMR applications in chemistry, structural
biology and materials research, such as scalar couplings (which require a resolution
of less than ten hertz) and small chemical shifts (which require a
resolution of around one part per million of the nuclear Larmor frequency).
Conventional, inductively detected NMR can provide the necessary high spectral
resolution, but its limited sensitivity typically requires millimetre-scale samples,
precluding applications that involve smaller samples, such as picolitre-volume
