Soo-hyon Phark is currently working as a PI at Center for Quantum Nanoscience (QNS) of Ins tute for Basic Science (IBS), where he is a leader of the research team "Atomic spin qubits on surfaces" using scanning tunneling microscopy (STM). He got his PhD in Solid State Physics from Seoul Na onal University (SNU, S. Korea) in 2006 for an experimental research on single molecule magnets on surface using scanning probes. Then, he had worked as postdoctoral researchers at SNU for 3 years and at Max-Planck-Ins tute of Microstructure Physics for 5 years. His major has been STM studies on surface nanostructures of oxides/metal, perovskite materials, graphene, and magne c nanostructures at UHV and low temperature. In par cular, he has performed spin-polarized STM/S of various magne c nanostructures, such as bilayer Co and Fe nanoislands on Cu, and studied spin-resolved electronic structures of ferromagnets and non collinear spin orders confined in nanostructures. He joined QNS from Oct 2016 and contributed to the setup processes of the center for the first few years. From 2019, he has been leading the project "Electron Spin Qubit Pla orms on Surfaces" using low-temperature STM equipped with electron spin resonance (ESR). He has developed a novel qubit pla orm using atomic single spins on a solid surface for the first me and demonstrated quantum-coherent manipula on of mul-qubit systems (2023). In recogni on of these pioneering contribu ons to the Quantum-coherent Nanoscience field, he has been awarded the 'Minister's Commenda on for Outstanding Scien sts of the Year 2024' from Korean Ministry of Science and ICT and won 'The Best Award in Sciences and Infrastructures of the 100 Na onal R&D Achievements' from Korean Ministry of Science and ICT in 2025. His research ar cle for the implementa on of atom-by atom mul-frequency ESR technique has also been chosen as 'The 1st ACS Nano Impact Awards' from American Chemical Society in 2025. Currently, he con nues and extends the projects using various atomic/molecular single spins towards quantum informa on science/technology using the bo om-up approach.
