Japan's Riken research institute aims to integrate quantum computing technology with its Fugaku supercomputer by 2025 and enable the real-world use of quantum computing. Riken reportedly intends to establish a communications link between a quantum computer and Fugaku, the world's second-fastest supercomputer, to overcome the need for extremely cold environments for quantum computers. The concept is to have only core calculations on the quantum machine, while Fugaku would organise and reinforce the various outputs to approach the right solution.

The institute also intends to work with a group of companies including Toyota Motor, Hitachi, and Sony Group to promote the use of computing infrastructure that combines quantum technology with supercomputers.
