In this project, we aim to develop a novel quantum electronics based on the coupling between spin and orbital motion of electrons in solids. We choose three-dimensional (3D) topological insulators, which have attracted great interests of contemporary materials science, as an ideal laboratory to study the spin-orbit coupling. A 3D topological insulator consists of a bulk insulating state and a conducting surface states which has a linear dispersion relation similar to graphene. Therefore exotic electro-magnetic responses are anticipated due to the relativistic

Negatively-charged nitrogen-vacancy (NV) centers in diamond is one of promising candidates for qubit and quantum sensors, because its electric spin states can be easily initialized, manipulated, and read-out by irradiating light and microwave with long coherence time. Hayase grout at Keio university aims to realize highly-sensitive quantum sensors utilizing quantum coherence of electric spins in diamond.
It is important to control positon and orientation of NV centers and to elongate coherence time of NV centers for improving sensitivity of quantum sensors. Hayase group has create new

We demonstrated highly sensitive motion detection in a mechanical resonator using the quantum transport in a semiconductor quantum dot. The mechanical resonators are widely used for various sensors in order to detect minute mass and weak force.
