Single-spin scanning with NV centers
Nitrogen-vacancy (NV) centers in diamond provide a unique platform for quantum sensing, enabling the detection of magnetic, electric, and thermal signals at the nanoscale.
With a QZabre NV scanning microscope — the first installed in Korea — we study solids, imaging magnetic textures and spin dynamics at the nanoscale by combining tip-scanning and confocal magnetometry.
Semiconductor device inspection with quantum sensors
We aim to develop a non-destructive semiconductor device inspection technique using quantum sensors.
Unlike conventional optical methods, quantum sensing enables direct mapping of current density and magnetic fields inside semiconductor chips — identifying defects without damaging the device.
Quantum devices for sensing, control & navigation
We aim to develop next-generation magnetic sensors based on quantum sensing — including ultra-sensitive RF sensors and amplifiers toward precise single-qubit control.
Looking further ahead, we hope to build a precision quantum compass for ultra-accurate navigation that could go beyond the limits of classical devices.
