About
SDT Inc., also known as Quantum Standard Technology, is a South Korean quantum technology company founded in 2017 with headquarters in Seoul. It works on quantum computing, quantum cloud, quantum communication, and quantum sensing commercialization, and it is leading the development of South Korea's first full-stack quantum computer. SDT was founded by CEO Jiwon Yune, who studied physics and electronic engineering at MIT and worked as a researcher at the MIT-Harvard University Research Center and the KIST Quantum Information Research Center. SDT is jointly developing quantum processing units based on silicon spin and diamond nitrogen-vacancy quantum technologies with Seoul National University and the Korea Institute of Science and Technology. It is developing a 3D qubit array architecture planned for the first half of 2025, and it is targeting a 64-qubit superconducting quantum computer by the first half of 2026 and photonic integrated circuit quantum computers by 2027. The company plans to build quantum computing data centers for cloud services and is advancing South Korea's National Strategy for Quantum Technology while building the domestic quantum ecosystem. In August 2024, SDT secured 10 billion KRW, approximately $7.5 million USD, in Pre-IPO investment from Shinhan Venture Investment to commercialize quantum computers. In 2025, SDT secured an additional 100 billion KRW from Shin Hventure, bringing total investment to 200 billion KRW, roughly $145M USD. In January 2026, SDT raised a further 30 billion KRW from Praxis Capital.
