An international research team led by Professor Hosung Seo at Sungkyunkwan University (SKKU)—in collaboration with researchers at the University of Wisconsin–Madison and the University of Washington—has computationally identified a novel atomic defect in zinc oxide (ZnO) capable of functioning as a high-fidelity “spin qubit.” Published in PRX Quantum, the findings propose a molybdenum-oxygen-vacancy complex [(MoZnvO)2+] as an optically addressable, deep-level spin-triplet defect. The discovery marks the first time a robust, room-temperature spin qubit has been identified in ZnO, a wide-bandgap semiconductor already deeply integrated into global commercial fabrication processes.
