AboutAbout the lab
Researching integrated circuits with extremely low energy consumption
The Yoshikawa Lab researches integrated circuits with extremely low energy consumption in order to realize the advanced information society of the future.
There are estimates that building a next-generation supercomputer from CMOS integrated circuits would require very large power consumption.
The lab therefore researches superconducting integrated circuits that are far more power-efficient than CMOS integrated circuits, even when the energy needed for cryogenic cooling is included.
Its goal is to spread this technology toward the realization of future high-end computers.
Key terms
- CMOS integrated circuit
- A type of integrated circuit that uses semiconductors. It is the benchmark against which this lab compares power consumption.
- Superconducting integrated circuit
- An integrated circuit that uses superconductivity. The lab states that it is more power-efficient than CMOS even when cooling is included.
- Cryogenic cooling
- Cooling an integrated circuit to an extremely low temperature. The comparison also takes this energy into account.
