OIST Spin-Out Funding and Licensing Secured by Qubitcore to Lead Japan’s Ion-Trap Quantum Computers
A major step towards the widespread use of Japanese-made ion-trap quantum computers has been reported by Qubitcore Inc., a business that was spun out of the Okinawa Institute of Science and Technology (OIST). The company, which has its headquarters in Yokohama, Kanagawa Prefecture, has inked an exclusive intellectual property (IP) licensing deal with OIST and successfully closed a pre-seed fundraising round spearheaded by the Okinawa Institute of Science and Technology Lifetime Ventures Fund. This agreement represents a significant advancement in fault-tolerant quantum computing systems and will go into effect on June 1, 2025.

Distributed Architecture for Fault-Tolerant Quantum Computing
The main goal of Qubitcore is to use optical resonators and ion trap technology to create distributed quantum computing platforms. Qubitcore will inherit and expand upon the noteworthy scientific accomplishments of OIST’s Experimental Quantum Information Physics Unit through the exclusive licensing arrangement. Okinawa Institute of Science and Technology Innovation has provided some funding for this research through its Proof of Concept (POC) initiative.
Assistant Professor Hiroki Takahashi is the head of the Experimental Quantum Information Physics Unit and the project manager for Moonshot R&D Program Goal 6 of the Japan Cabinet Office. Through the “Realization of a fault-tolerant universal quantum computer that will dramatically advance economy, industry, and security by 2050,” this ambitious national program seeks to construct fault-tolerant quantum computers that make use of photonic interconnects and ion traps.
The novel strategy employed by Qubitcore makes use of a distributed quantum computing (DQC) architecture. By integrating ion-trap modules created by Okinawa Institute of Science and Technology with integrated optical cavities, resonant structures that capture light for effective ion–photon interaction, and a photonic connection network, this architecture overcomes the scaling constraints of traditional quantum processing units (QPUs). High-speed, high-fidelity distant entanglement between modules is made possible by this configuration, providing a breakthrough for scalable distributed quantum computing. Qubitcore seeks to build large-scale systems that were previously difficult to accomplish with conventional ion-trap techniques by optimizing the performance of individual QPUs and optically connecting them, opening the door for useful fault-tolerant quantum computers (FTQCs).

Pre-Seed Funding and Ambitious Roadmap
Accelerating Qubitcore’s early-stage development will be made possible by the pre-seed investment obtained from the Okinawa Institute of Science and Technology Lifetime Ventures Fund. The funds will be used to hire specialized research staff, prototype ion-trap modules with built-in optical cavities, and buy experimental equipment. Qubitcore also intends to use non-dilutive funding, such as possible public funds from initiatives like NEDO, to augment equity financing.
A multi-phase roadmap for the widespread implementation of FTQCs has been delineated by Qubitcore:
- 2028: Present a first-generation experimental quantum error correcting testbed system.
- 2029: Present a second-generation prototype that highlights photonic connections across modules, indicating architectural possibilities for future development in the direction of 1,000-qubit-class computers.
- By 2030: Target commercial-grade deployment based on this architecture.
Focused research and development (R&D) activities in high-efficiency quantum error correction, experimental validation of photonic links, and modular ion-trap integration will help achieve these goals. Additionally, the business plans to start the early stages of developing a control platform for upcoming services involving quantum computing.
Statements from Key Stakeholders
“They are honoured to join the community of Okinawa Institute of Science and Technology-originated startups and to receive support from Lifetime Ventures,” said Ryuta Watanuki, founder and CEO of Qubitcore Inc. This milestone marks a major advancement in the commercialization of Japan’s first ion-trap quantum computer to be created domestically. They are dedicated to integrating quantum computing into society as they develop the technology with industrial use cases in mind.
“It is extremely meaningful to see research on quantum photonic interconnects using ion traps, which I have pursued at OIST, evolve into tangible initiatives for social implementation,” said Hiroki Takahashi, assistant professor at OIST and co-founder and CSO of Qubitcore Inc. I anticipate that Okinawa Institute of Science and Technology, Qubitcore, and academics from Japan and beyond will work together to make quick advances in research and development.
Japan has established decades of foundational expertise in photonics and ion-trap technologies, and in recent years, this has been further accelerated by significant national support, most notably through Moonshot Goal 6, which allots a total of JPY 148 billion (approximately USD 1.0 billion) to advance fault-tolerant universal quantum computers, according to Ryosuke Kimura, General Partner at Lifetime Ventures. This combination of global talent, national strategy, and profound technical tradition, in my opinion, signals the start of a quantum hardware platform from Japan that might have an impact on the entire world.
To convert state-of-the-art research into workable, real-world quantum systems that will help the economy, industry, and security, this partnership between the Okinawa Institute of Science and Technology and Qubitcore marks a turning point for quantum computing in Japan.
