Cyber-Physical Computing Lab
Machine-translated · View original
A lab that explores the mechanisms of future computers through superconducting, quantum, and optical technologies.
AboutAbout the lab
Exploring what future computers should be.
The Cyber-Physical Computing Lab studies new computing mechanisms and their applications.
The lab explores what future computers should look like in order to efficiently process, in the cyber world, the vast amounts of data generated in the real world and return the results to the real world.
Looking across everything from hardware to software, the lab investigates computer architectures that are optimal for the system as a whole.
Its work includes computers that use new devices such as superconducting, quantum, and optical devices, as well as secure and environmentally conscious computers.
Key terms
- Computer architecture
- The basic structure and design approach of a computer. It determines how hardware and software are connected.
- Superconductivity
- A phenomenon in which electrical resistance disappears at extremely low temperatures. The lab aims to build high-speed computers using circuits that operate in this state.
- Accelerator
- A dedicated computing device for performing specific processing quickly. Here, it refers to devices specialized for particular uses such as AI processing.

ResearchResearch themes
The lab aims to create new computer architectures based on the integration of information science and electrical and electronic engineering, and to develop new application technologies that take advantage of overwhelming computing power. Its research takes a view of the whole system, from devices and circuits to applications.
*Illustrative imageHigh-speed processors using superconductivity
The lab aims for a next-generation microprocessor operating above 100 GHz, 30 to 50 times today's clock frequencies. It has successfully demonstrated a multiplier circuit, based on a new type of arithmetic circuit, that runs at about 50 GHz and 5 mW, and is now working to develop it into a processor.
*Illustrative imageQuantum computer architecture
Research on quantum computers has centered on the device level, and the architecture technology needed to build them as full systems remains largely unexplored. The lab investigates hybrid architectures that combine conventional computers with quantum computers.
*Illustrative imageComputers using light
With advances in silicon photonics and nanophotonics making it possible to integrate large numbers of optical elements, the lab aims to realize computers that operate at the speed of light. It also targets new accelerators specialized for tasks such as AI processing.
*Illustrative imageHardware-based security
To keep IoT systems safe, the lab aims to build security technology into CPUs and other hardware so that malware cannot be executed, or is detected and dealt with early. It also works on machine-learning-based detection and on techniques for hiding memory access information.
