Quantum Magnetic Sensing Group investigates quantum physical properties and explores industrial applications by developing high-sensitivity quantum magnetic sensors and high-precision magnetic metrology.
Our sensing technology enables quantum magnetic imaging with a spatial resolution from millimeter to nanometer and with a temporal resolution down to femtosecond. We establish various infrastructures for measuring spin-based quantum properties, aiming for the international standardization of quantum magnetic metrology.
