A research team affiliated with UNIST has unveiled a quantum device, capable of ultra-fast operation, a key step toward realizing technologies like 6G communications. This innovation overcomes a major hurdle that has long limited the durability of such devices under high electrical fields.

Professor Hyeong-Ryeol Park from the Department of Physics at UNIST, in collaboration with Professor Sang Woon Lee at Ajou University, has developed a terahertz quantum device that can operate reliably without suffering damage from intense electric fields—something that has been a challenge for existing technologies.
