Research

The development of our society has been supported by drastic improvement of the computation system based on the semiconductor integrated circuit technology. However, the semiconductor circuit technology is facing serious problems, such as saturation of operating speed and increase in power consumption caused by the physical limitation of the fabrication technology.

We have been studying novel computation system based on the superconductor circuit technology. By using the superconductor devices, ultra-high-speed and ultra-energy-efficient computation system can be build. Our main research themes are following.

• Study on superconductor digital circuit that can perform logic operation at the frequency of several hundreds of GHz with extremely low power consumption.
• Development of quantum annealing machine using superconductor circuit that can efficiently solve optimization problems by utilizing macroscopic quantum effects in superconductor.
• Study on artificial superconductor neural network that mimics the human brain and can solve specific problems quite efficiently.
