Low-energy High-performance Computing based on Superconducting Technology

Huge heat generation from logic circuits limits the performance of recent high-end computing systems, and their large power consumption becomes a social problem nowadays. Superconducting computing has potential to overcome the problem due to its extremely low-energy consumption with very high performance. In this presentation we will show recent progresses of low-energy high-performance superconducting computing. After the review of current research activities in Japan as well as in the world, we will show the ultimate-low-energy superconducting computing technology based on adiabatic and reversible operation of logic. It is emphasized that the superconducting logic is the technology that breaks through the thermal limit in computation.
