Hyoungwoo double-majored in Physics and Chemistry at KAIST. In Chemistry, he primarily focused on physical chemistry, while in Physics, he became particularly interested in courses exploring the interaction between light and atoms. These experiences led him to develop a strong interest in quantum science and quantum computing. His current research interests include quantum error correction and digital-analog quantum simulation. He is especially interested in understanding how quantum systems can be reliably controlled and utilized for computation and simulation. Outside of research, Hyoungwoo enjoys listening to music and playing the guitar.

Woojin studied Physics for his undergraduate degree, with interests in atomic physics. At the KAIST OQT, his research focuses on high-fidelity single-qubit gates and quantum error correction in large-scale atomic qubit arrays. He is particularly interested in developing scalable architectures toward large-scale logical-qubit quantum computing. Outside the lab, Woojin enjoys playing video games across various genres and platforms.

Minho studied Physics for his undergraduate degree with interest in quantum optics and quantum information. Before joining KAIST OQT, he worked on engineering photonic crystal cavities for versatile polarization control. His current focus is on developing the control interface for neutral atom-quantum computing and non-destructive state detection. Minho enjoys listening to music and playing guitar and drums.

Unggyun studied Physics for his undergraduate with interests on condensed matter physics and, more recently, quantum information science. At the KAIST OQT, his research is on precision qubit control and quantum simulation. Unggyun enjoys cooking on his days off and tasting new ingredients.

Sangjin studied Physics and EE for his undergraduate. He participated in educational activities at KAIST where he designed a smart-phone experiment to demo the conservation of angular momenta to middle school students. He was also involved in research to quantitatively analyze music from its statistical perspectives. Sangjin's current research interest is in quantum computing technologies: at the KAIST OQT, his research focus is on the single-atom feedback control. Outside the lab, Sangjin enjoys street dancing - especially Poppin - and playing the piano.

Seuk studied Physics for his undergraduate, during which he participated in several projects including an experimental demonstration of Bell inequality violation. He also participated in fabricating and exhibiting structures that model the motion and size of the Sun, Earth and Moon. At the KAIST OQT, his research focuses on local addressing of neutral atoms in optical tweezer arrays.

Sanghyo studied Physics for his undergraduate with interests on quantum algorithms and quantum computing. At the KAIST OQT, his research focus is on developing hybrid quantum computing architectures. Sanghyo enjoys biking and snowboarding outside of the lab.

Minhyeok studied Applied Physics for his undergraduate with a particular interest in implementing quantum information science with the use of lasers and optics. He also organized a team for studying the distribution characteristics of microplastics buoying on urban rivers. At the KAIST OQT, Minhyeok's research is on optical imaging interfaces for quantum-emitter platforms.

Keunyoung is studying Physics and Electrical Engineering at KAIST. Before entering KAIST, he experimentally studied the quantum entanglement and Bell's argument in high school. His current research interests are to build quantum systems for computing and sensing applications. At the KAIST OQT, his research focus is on designing a scalable system architecture of controlling atomic qubits. Keunyoung enjoys sports, such as baseball, cycling and running.

Dongbeom studied Physics for his undergraduate degree with interests in quantum mechanics and quantum computing. At the KAIST OQT, Dongbeom's research is on developing a neutral- atom quantum information processor. Dongbeom loves listening to music, and watching movies . He often writes reviews about music and movies.

Suwan studied Physics and Computer science with interest in both quantum computing and classical computer.  Suwan enjoyed studying interactions between the atom and the light during undergraduate course. At KAIST OQT, his research is on single neutral-atom control and quantum ensemble sensing. Suwan enjoys playing the violin, listening to music and sports.
