Researchers have developed the world’s first quantum sensor capable of sensing atomic-scale electric and magnetic fields using a single molecule attached to a scanning tunneling microscope. This breakthrough provides unparalleled spatial resolution, akin to an MRI, enabling deep insights into material properties at the atomic level. Credit: SciTechDaily.com
A quantum sensor is a technology that uses quantum mechanical phenomena such as the spin of an electron or the entanglement of quantum states for precise measurements. Several types of quantum sensors have been developed over the past years. While many quantum sensors are able to sense electric and magnetic fields, it was believed that atomic-scale spatial resolution cannot be mastered simultaneously.
“What makes this achievement so striking is that we use an exquisitely engineered quantum object to resolve fundamental atomic properties from the bottom up. Preceding techniques for visualizing materials use large, bulky probes to try to analyze tiny atomic features,” stresses QNS’s lead author Dr. Dimitry Borodin. “You have to be small to see small.
