Abstract: | Color centers in wide-bandgap semiconductors have emerged as a leading platform in the field of quantum sensing, broadly defined as the use of qubits to measure environmental parameters. Here at UNM, we are using Nitrogen-Vacancy (NV) spin qubits in diamond to image magnetic phenomena in condensed-matter and biological systems over a broad range of length scales. At the nanometer scale, we build diamond magnetic microscopes to image, for example, the paramagnetic nanocrystals produced by malaria parasites. At the micrometer scale, we embed diamond quantum sensors inside microfluidic chips to perform nuclear magnetic resonance spectroscopy at the scale of single cells. At the millimeter scale, we use magnetic flux concentrators to detect femtotesla-level magnetic fields, with potential applications in medical imaging, geoscience, and even dark matter detection. I will provide an overview of the field, discuss recent results and ongoing challenges, and outline future directions. | |
