About
Qubitcore is a Yokohama-based quantum computing startup, founded in July 2024 as a spinoff from the Okinawa Institute of Science and Technology (OIST). The company develops distributed quantum computing systems built on ion trap technology with photonic interconnects. Led by CEO Ryuta Watanuki and CSO Prof. Takahashi, Qubitcore raised pre-seed funding in January 2025, and in April 2026 it raised a JPY 1.53 billion seed round led by SBI Investment, advancing Japan's first trapped ion quantum computer initiative. Its roadmap calls for a testbed system by 2028, a 1,000-qubit prototype by 2029, and commercial deployment by 2030. The company's R&D center sits at OIST in Okinawa, using the institute's research facilities. Through 2025, Qubitcore continued developing its distributed ion trap architecture, marking Japan's entry into trapped ion quantum computing.
