Similar to the way that a conventional magnetic resonance imaging (MRI) machine uses large magnets to generate 3D images, physicists have developed a proposal for a quantum nano-MRI machine that would use the magnetic properties of a single atomic qubit to generate 3D images with angstrom-level (0.1-nanometer) resolution. The new technique could lead to the development of single-molecule microscopes for imaging biomolecules, with applications in drug discovery and better understanding diseases.
The researchers, led by Lloyd Hollenberg, a physics professor at the University of Melbourne, have published a paper on the new technique in a recent issue of Nature Communications.
