Quantum Computing

The Itoh Research Group is actively pursuing to realize the ultimate silicon computer that uses individual silicon atoms to perform computations.

Kohei Itoh Research Group

This research group focuses on realizing the complete manipulation of semiconductor isotopes using state-of-the-art nanotechnology.

The research carried out in this group covers a wide variety of novel quantum physics emerging in low-dimensional semiconductor structures and their applications to a new class of devices such as quantum computers.


In Spintronics research, the direction of electron spin vectors are used to represent binary digits "1"s and "0"s.

A spin vector pointing up represents a "1" and a spin vector pointing down represents a "0".

With this intuitively simple setup, Quantum Computers of the future will depend on these electron spin vectors for storing and computing information.

A little help from Japanese Phonetics and by using a series of 3 directional arrows to represent binary digits "110", we were able to create a fitting logo.
