Quantum Sensing of Correlated Electron Systems
Strongly correlated systems are one of the most interesting and challenging fields in physics. To understand the physics of quantum phenomena such as superconductivity and magnetism, measurements with ultimate sensitivity is needed. We have developed a powerful tool of quantum sensing under extreme conditions. With it, we are exploring many body physics .

Research Highlights
Coherence enhancement of solid-state qubits
Solids state qubit based quantum sensing has emerged as one of the most promising quantum applications. We solve a bottle neck problem of short decoherent time of shallow implanted solid state qubit by several methods. The decoherence time increase dramatically, up to 20 folds. These methods will pave the way of solid state quantum sensing.
