Japan's first domestically produced quantum computer started operation on March 27. The Institute of Physical and Chemical Research (RIKEN) also intends to make the computer available via the Internet, RIKEN announced the week before on March 24. Access is being considered for researchers, technical personnel and other professionals from universities, private companies and other organizations.
The United States and other countries hold the lead in the development of quantum computers. It is hoped that the advent of this domestically developed quantum computer will give a boost to Japan's scientific and industrial competitiveness.
Global Competition at the Quantum Level
Quantum computers are expected to be able to perform calculations faster than current supercomputers and solve complex problems. Global competition in the development of quantum computers is intensifying. They have the potential for application in a wide range of fields. Among them are the development of new materials, drug discovery, and the forecasting for financial markets and economic trends.
In April of 2021, the Japanese government formulated a strategy for the development of a homegrown quantum computer. Their target was to begin by the end of the current fiscal year (in April 2023). Since then, the RIKEN Center for Quantum Computing (RQC) in Wako City, Saitama Prefecture has been engaged in developing such a machine.
How It Works
The RIKEN quantum computer uses superconducting circuits that eliminate electrical resistance by cooling to extremely low temperatures. RQC's current director Yasunobu Nakamura, was one of the pioneers in devising this superconducting method for quantum computing. In his current position he also leads the quantum computer development effort.
Organizations participating in the development of the computer besides RQC include Osaka University, Fujitsu and the National Institute of Advanced Industrial Science and Technology (AIST).
Parties wishing to use the new quantum computer after signing joint research agreements with RIKEN are now being solicited.
