- Abstract
- 최근 차세대 컴퓨팅 혁신기술로 주목받고 있는 양자컴퓨팅을 위해 본 연구에서는 양자컴퓨팅 어플리케이션을 위한 극저온 양자 상태 제어 및 판독 회로기술을 연구하고자 한다. 집적화가 필요하기에 CMOS 공정을 사용하며 핵심회로는 I/Q Mixer, Group Delay Equalizer, Cable Equalizer가 있다. 본 연구에서는 핵심회로를 위한 단위회로인 저잡음 증폭기를 설계하였다. 극저온 집적화를 통해 상온에서 발생하는 열잡음 문제와 복잡한 배선 문제를 해결하고자 한다.
To advance quantum computing, a next-generation computing innovation, this study aims to research cryogenic quantum state control and readout circuit technology for quantum computing applications. Due to the need for integration, CMOS processes will be used, with key circuits including the I/Q Mixer, Group Delay Equalizer, and Cable Equalizer. In this study, we have designed a Low Noise Amplifier, which is a unit circuit for the key circuits. By achieving cryogenic integration, we seek to address the issues of thermal noise and complex wiring that occur at room temperature.
