Quantum Science with Single Atoms and Molecules on Surfaces

Explore quantum science through the manipulation of individual atoms and molecules on surfaces in this seminar by Philip Willke from the Karlsruhe Institute of Technology. Discover how the combination of electron spin resonance (ESR) and scanning tunneling microscopy (STM) creates a revolutionary platform for coherent control of spins on surfaces, enabling the addressing of individual atoms with exceptional energy resolution. Learn about high-resolution magnetic sensing capabilities, including the resolution of hyperfine interactions between electron and nuclear spins of individual atoms. Examine the extension of this technique to achieve spin resonance on individual molecules, opening new possibilities in molecular quantum technologies. Understand how molecular self-assembly can organize spins into larger structures and how on-surface chemistry techniques can be applied to quantum systems. See practical demonstrations of how tip-assisted on-surface assembly can construct new complexes with improved dynamic spin properties that can be coherently controlled, showcasing the potential for future quantum devices built from fundamental quantum building blocks.
