Research

We are studying the application of quantum mechanical phenomena to high performance sensing technique. Photon Factory at KEK (Tsukuba) offers materials structure research with synchrotron radiation. The pulsed nature of synchrotron X-ray especially enables structural dynamics study of materials at picosecond time resolution.

RIKEN Advanced Research Institute conducts Terahertz(THz)-wave research and development at Sendai facility. The themes include THz quantum detection by superconductor devices, THz photonics and their applications to various fields.

Finally, as the cooperation with NTT Basic Research Laboratories, we are studying ultrasmall force and displacement detection using a small bar called as a cantilever. We have integrated low-dimensional quantum structures to enhance the detection sensitivity. This high-performance sensing technique provides a novel way to study quantum physics in low-dimensional structures.
