Fields of research
We believe that the next generation of problems in science, technology and society need to be solved on the most fundamental length scale of matter, the atomic scale. We do that by imaging and manipulating atoms and molecules using a scanning tunneling microscope. In this way, we can investigate and control their quantum properties with ultimate precision. At the heart our research focuses on the quantum coherent control of new atomic-scale spin systems.
We use in particular scanning tunneling microscopy in combination with electron spin resonance to resolve and control quantum systems on a microscopic scale and atom by atom. This novel combination of experimental methods allowed us to use single atoms as highly precise magnetic sensors, it allowed us to detect and control the nuclear spin inside a single atom and we could also perform the worlds smallest magnetic resonance image of just a single atom. Ultimately, we want to create a new solid-state architecture for magnetic sensing and quantum information processing operating on the atomic scale.
