QUASAR Lab

Quantum Sensing with Advanced Device Research · 첨단양자센싱소자 연구실

We build room-temperature diamond nitrogen-vacancy (NV) quantum sensors. Using the quantum state of single atomic spins, the lab images magnetic fields at the nanoscale, inspects semiconductor devices without damaging them, and develops next-generation quantum devices for ultra-sensitive sensing and navigation — bridging quantum information and real-world applications.

Research

What we do

Integrating diamond NV-center qubits, spintronics, and microdevices for ultra-sensitive sensing and advanced materials science.
