고체 양자 구조를 기반으로 한 고효율 양자 광/스핀 소자 개발, 양자 측정 및 상호작용 구현, 양자 정보 응용 기술 개발 (https://www.qupid.unist.ac.kr) We study various solid-state quantum systems, such as quantum dots, defects, and newly emerging quantum materials. Our research aims to generate and control photonic and spin qubits from solid-state quantum structures to implement scalable and integrated quantum systems. These systems will provide chip-scale platforms for quantum information technologies, such as quantum communication, quantum sensing, and quantum computing.
