Quantum Information Science and Engineering
Realizing quantum computers and quantum communication.
Introduction
The mid-to-late 20th century is recognized as a period of significant human civilization advancement, marked by the remarkable development of electronics. Large, vacuum-tube computers were first utilized during World War II for military purposes such as code-breaking, ballistic trajectory calculation, and weapon design, marking the start of the information technology era. Subsequently, rapid advances in semiconductor technology led to the miniaturization of computers. Following the popularization of personal computers, various devices like laptops, smartphones, and tablets have become deeply integrated into daily life. At the same time, innovations in the internet and communication technologies enabled digital social activities such as e-commerce, online banking, remote conferencing, and social media, fundamentally changing individual lives and society itself.
Today we face yet another major technological shift. This shift is centered on the quantum computer, which offers the potential to solve highly complex problems currently impossible for classical computers to solve. Quantum computers are expected to be used in areas such as new drug discovery and personalized medicine, and they are also anticipated to contribute to overcoming bottlenecks in AI technology by boosting computational efficiency. Furthermore, there is a need for a quantum internet to connect quantum systems globally.
Because quantum computers could break current RSA-based encryption, the development of quantum-safe communication technologies is critical. In addition, high-sensitivity quantum sensor technology—capable of precisely measuring and controlling quantum states—is also emerging as a core element of the quantum information infrastructure. Only by integrating these technologies can we truly enter the quantum information age.
The Department of Quantum Information Science and Engineering aims to cultivate professionals with the essential skills (theory and practice) needed to develop quantum computers, the quantum internet, and quantum sensor technologies. We offer integrated education in the foundational theories of quantum information science and hands-on practice, and we seek to enhance practical adaptability through industry-academia-research linked curricula.

Career Path after Graduation
Upon graduation, students can find careers in various areas including quantum computing, quantum communication, and quantum sensing. Domestic semiconductor companies like Samsung Electronics and SK Hynix need more experts in quantum hardware, device technology, and circuit design. Telecommunication companies and defense contractors (such as SK Telecom and KT) require experts with skills in quantum cryptography, communication, and developing strong security systems. Furthermore, global leaders in quantum computer development, including Google, IBM, IONQ, and PsiQuantum, provide chances to work abroad in international companies and research institutes. Graduates can also work on product development, system design, and algorithms at quantum tech startups and mid-sized companies that use convergence tech. Government-funded research institutes (e.g., KIST, ETRI, KRISS) always hire researchers for areas like quantum sensors, quantum networks, and quantum algorithms, so research is a great option too.
