Quantum sensing uses spin coherence to probe physical parameters with exceptional precision and capability. One of the main tools in this field is atomic magnetometry, which relies on optically pumped atomic alignment to directly measure magnetic fields with the highest sensitivity to date. By integrating acoustic force with an atomic magnetometer, we have invented super-resolution force spectroscopy (SURFS) that resolves intermolecular bonds with an unprecedented 0.3 pN resolution. The new technique has a much larger field-of-view than the usual single-molecule force techniques and has
Xu et al. (Sun,) studied this question.
