SKKU Researchers Identify Room-Temperature “Spin Qubit” Defect in Zinc Oxide Semiconductors

Researchers at Sungkyunkwan University, in collaboration with the University of Wisconsin–Madison and the University of Washington, have discovered a novel atomic defect in zinc oxide semiconductors that can function as a high-fidelity spin qubit at room temperature¹. This breakthrough has significant implications for the development of quantum computing, as it could enable the creation of more efficient and stable quantum systems. The defect, identified through a computational workflow, has the potential to revolutionize the field of quantum computing by providing a reliable and consistent means of storing and manipulating quantum information. The use of zinc oxide semiconductors, a common material in electronic devices, could also facilitate the integration of quantum computing into existing technologies. This discovery matters to practitioners because it brings us closer to realizing the potential of quantum computing, which could fundamentally change the way we approach computation and cryptography.
