Semiconductor Quantum Dot

A semiconductor quantum dot is a quantum device in which electrons can be controlled on a one-by-one basis. Inside of them, atom-like shell structures are formed, which are also called artificial atoms. We are investigating quantum information processing devices with new functions by combining quantum dots with optical resonators in the terahertz band.

Ultrastrong Light-Matter Coupling

Confining light to a small area by creating semiconductor or metal nanostructures can extremely enhance the interaction between light and matter. Our research is aimed at exploring novel quantum phenomena due to the significant coupling of light and matter, and their application to quantum devices.

Research

In recent quantum science and technology, such as quantum information processing technologies, the hybridization of different quantum systems has been extensively studied in order to convert quantum information between different quantum systems or to realize new quantum functions that do not exist in individual quantum systems. In our research group, we study the new physics that appears in quantum hybrid systems, where electrons strongly interact with terahertz-band electromagnetic waves, using controllable quantum nanostructures such as semiconductor quantum dots.
