Fujitsu Builds Japan's Second Self Developed Quantum Computer: 64 Quantum Bits

On October 6th, Fujitsu announced the successful development of Japan's first privately owned quantum computer, as well as Japan's second self-developed quantum computer. Similar to the first, it has 64 quantum bits.

The head of Fujitsu Quantum Laboratory, Nobutaro Sato, stated that "this is a huge achievement", marking the availability of this quantum computer for external companies and research institutions.

It is understood that Fujitsu collaborated with the government supported research institution Riken in 2021 to establish a research and development center in Hokugawa City, where both parties jointly developed quantum computers. The Japan Institute of Physics and Chemistry launched Japan's first quantum computer in March 2023, with 64 quantum bits and a low-temperature superconducting circuit design.

At present, Japan's research and development progress in the quantum field lags behind that of China and the United States, but a development plan has already been formulated. Fujitsu plans to combine quantum computers with supercomputers to improve computing power. In the future, Fujitsu will put quantum computers into practical applications to simulate molecular configurations, analyze material properties, and improve the development efficiency of new materials and drugs. In addition, Fujitsu also plans to collaborate with Tokyo Electronics, Fuji Film, Mitsubishi Chemical Group, and Mizuho DL Financial Technology Company.

According to McKinsey&Company's prediction, quantum computing is expected to generate an economic scale of up to $1.3 trillion in fields such as financial services, chemicals, and life sciences by 2035. Riken has announced that Japan's first quantum computer will be named "A", which is a homophone of a Japanese word meaning "wisdom".
