The world's first commercial quantum computer, built in Japan, has begun operations.

The University of Tokyo and IBM Corp. have begun operations of Japan's first commercial-use quantum computer, marking the country's entry into a fiercely competitive sector dominated by the United States and Chinese researchers.

Upcoming systems developed by a U.S. technology business and given access to exclusive use rights at a university in Kanagawa Prefecture were put in place at Kawasaki Business Incubation Center in southwest Tokyo.

A collaborative effort between the industry and academia is set to begin in 2020, featuring Toyota Motor Corporation, Sony Group Corporation, and Mitsubishi Chemical Holdings Corporation. It will focus on utilizing quantum computing for practical purposes and fostering human resources.

IBM is the first US-based corporation to build a second Quantum System One computer system, have created in Germany a few years before.

"Breathtaking progress is being made in industries where quantum computers are employed. I want to give the world an idea of my accomplishments. "University President Teruo Fujii made a statement at the ceremony where the computer's operations were officially launched on Tuesday.

Unlike ordinary computers, quantum computers use quanta, which are particles of light that have the properties of both waves and particles. Quantum computers can calculate scores of possibilities simultaneously rather than one at a time, as is the case with regular computers.

The pace at which it can tackle complex problems and processes is anticipated to be used in creating new pharmaceuticals and materials, devising financial models, and streamlining supply chains. This is also true of cryptography, which is required in the creation of the internet and digital currency.

"It is essential that the base has been established in Japan (for a quantum computer) since it helps to grow staff that is adept at operating it," said Hideyuki Mase, Senior Research Officer at the Japan Research Institute.

While the completion of the full-fledged operation of quantum computers still presents numerous technological hurdles, the race to build them has grown into an intense competition that is pitting the U.S. and China against each other.

"The foundation will allow us to engage international expertise, including in Asia. As Japan continues to invest in research and development, it is likely to become a significant competitive advantage. "Mase described the situation on the field.

Some several other companies and universities are members of the Quantum Innovation Initiative Consortium that have access to the system, including Keio University, Hitachi Ltd., Mitsubishi UFJ Financial Group Inc., and Yokogawa Electric Corp.
