Jiwon Yune
Founder & CEO
From a young age, he was fascinated by natural sciences and began his journey into quantum physics during high school by joining Professor Vladan Vuletić's laboratory in the Department of Physics at the Massachusetts Institute of Technology (MIT).
While pursuing his bachelor's and master's degrees in Physics and Electrical Engineering at MIT, he conducted research on key quantum computing technologies, including neutral atoms, diamond NV centers, ion traps, and photons, gaining a broad perspective and expertise in the quantum technology ecosystem.
Subsequently, he contributed to the advancement of quantum technology in South Korea at the Korea Institute of Science and Technology (KIST).
Building on the insights gained as a researcher, he founded SDT Inc. in 2017, embarking on a mission to integrate quantum technology into industry and everyday life. Leading the development of South Korea's first full-stack quantum computer and the expansion of the quantum technology ecosystem, he continues to drive SDT's growth.
