Quantum technologies promise revolutionary advances in computing, sensing and information processing. However, controlling individual quantum bits (qubits) at the atomic scale remains a major challenge because conventional approaches rely on magnetic fields, which are difficult to confine to a single molecule.
A research team at the Center for Quantum Nanoscience (QNS), led by Director Andreas Heinrich at the Institute for Basic Science (IBS), together with collaborators at the Karlsruhe Institute of Technology (KIT), has demonstrated that the quantum state of an individual magnetic molecule can instead be controlled electrically using a newly identified exchange-mediated mechanism. The study published in Nature Physics provides a new strategy for electrically controlling molecular quantum systems and could help pave the way for more scalable quantum technologies.
