SEOUL, Korea — Researchers at the Center for Quantum Nanoscience within the Institute for Basic Science (IBS) have made a major breakthrough in controlling the quantum properties of single atoms. In an international collaboration with IBM Research in San Jose, USA, using advanced and novel techniques, QNS scientists identified which mechanisms destroy the quantum properties of individual atoms by manipulating the magnetic state of a single iron atom on a thin insulator. Using a Scanning Tunneling Microscope, which utilizes an atomically sharp metal tip, they were able to precisely image individual iron atoms and measure and control the time that the iron atom can maintain its quantum behavior.
