Abstract

NMR on a chip Nuclear magnetic resonance (NMR), the analytical technique familiar in magnetic resonance imaging, tracks a quantum mechanical property of nuclei called spin, where each nucleus acts like a tiny barmagnet. Large coils and quite bulky samples are usually required to detect these magnets indirectly. But a new system makes it possible to detect spin directly, allowing NMR measurements on a nanoscale sample on a semiconductor chip. It also provides tighter control over nuclei than conventional NMR, so can probe nuclei containing multiple spin levels, one of the systems that can be used in quantum computing.
