Global Brain has made an additional investment in OptQC Corp. (OptQC), a Japanese startup aiming to develop commercial optical quantum computers, through its Global Brain Flagship Fund IX (GB-IX) as the lead investor. OptQC was founded in September 2024 to commercialize cutting-edge optical quantum computing technologies developed by the Furusawa-Endo Laboratory at the University of Tokyo, a global leader in this field. While quantum computers are gaining attention as the next-generation computing infrastructure capable of solving complex problems beyond the reach of classical computers, industrial applications require hardware with over one million qubits. OptQC’s optical quantum computers are expected to achieve this scale due to their superior scalability compared to superconducting and other quantum computing implementations. Additionally, they offer advantages such as lower power consumption and faster processing, positioning optical quantum computers as a potential ultimate form of quantum technology in the long term. Since Global Brain’s initial investment in January 2025, OptQC has been steadily advancing the development of its first commercial optical quantum computer, which is scheduled to become operational in April 2026. OptQC has also achieved significant milestones both technologically and commercially, including the selection of two research themes under New Energy and Industrial Technology Development Organization (NEDO)’s Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems. Through this additional investment, OptQC will accelerate research and development toward its second commercial machine. Global Brain will continue to support OptQC’s efforts to commercialize optical quantum computers and expand its business globally. Note: Global Brain announced its investment in OptQC through its GB-IX in January 2025.
