CQC2T researchers at the University of Melbourne have demonstrated a way to detect nuclear spins non-invasively using quantum technology, providing a new tool for materials science and biotechnology.
A nitrogen-vacancy (dark blue) quantum probe performing nanoscale nuclear magnetic resonance (NMR) on molecular hydrogen. A green laser controls the quantum state of the probe, which is tuned to the resonant frequency of target nuclear spins. The probe responds to the nuclear spins of the hydrogen atoms and provides a direct measurement via the red light emitted. Image credit: David A. Broadway/cqc2t.org
The team, led by CQC2T Deputy Director Prof Lloyd Hollenberg, has used a quantum probe to perform microwave-free nuclear magnetic resonance (NMR) spectroscopy at the nanoscale. The new technique overcomes significant limitations with existing approaches.
