IT services provider Fujitsu and Japanese research institute RIKEN have announced the development of a world-leading 256-qubit superconducting quantum computer, established at the RIKEN RQC-FUJITSU Collaboration Center. This new quantum computer builds upon the advanced technology of the 64-qubit iteration, launched with the support of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) in October 2023, and incorporates newly-developed high-density implementation techniques. This announcement marks another crucial step toward the practical application of superconducting quantum computers and unlocking their potential to grapple with some of the world’s most complex issues, according to a media release.
Both organizations will integrate the 256-qubit superconducting quantum computer into its platform for hybrid quantum computing lineup and offer it to companies and research institutions globally starting in the first quarter of fiscal 2025. The platform’s expansion from 64 to 256 qubits empowers users to tackle more complex challenges, including the analysis of larger molecules and the implementation and demonstration of sophisticated error correction algorithms. Moving forward, both organizations will further enhance the platform’s usability by working to enable seamless collaboration between quantum and classical computers, enabling the efficient execution of hybrid quantum-classical algorithms, the media release said.
Fujitsu and RIKEN’s 256-qubit superconducting quantum computer overcomes some key technical challenges, including appropriate cooling within the dilution refrigerator, which is achieved through the incorporation of high-density implementation and cutting-edge thermal design. Other key features include a scalable 3D connection structure and quadrupled implementation density within dilution refrigerator. Fujitsu and RIKEN will continue R&D efforts toward the launch of a 1,000-qubit computer, which is scheduled to be installed in a new building at Fujitsu Technology Park in 2026.
