Currently available computers consume much more energy than the fundamental bound, and the increase in energy consumption associated with computation is a serious problem.

This Research Project sets the problem of how to simultaneously achieve fast information processing and high energy efficiency, which are in a trade-off relationship. The research will be conducted both theoretically and experimentally from the perspective of thermodynamics of information, which has been pioneered by the Research Director. Specifically, we will establish a theory of the fundamental bound of energy required for fast information processing. Experimentally, interconversion between information and thermodynamic energy will be verified through control of thermal and quantum fluctuations. The obtained results would lead to new design principles of computers in the future.
