The world’s most advanced research data is often generated through state-of-the-art measurements, analysis techniques and instruments, and experimental techniques is evolving significantly. Understanding the physical behavior of these measurements, analysis techniques and actively will lead to new measurement and analysis methods that will open new frontiers both in physics and in the fusion of different fields. In Quantum Functional Measurement Group, we are developing quantum detectors using superconductors and conducting research on sensing using terahertz waves, a new electromagnetic wave region, based on the most advanced measurement and analysis techniques.
