OptQC Joins JST Moonshot Goal 6 Project

OptQC Corp. (Headquarters: Toshima-ku, Tokyo; Representative Director and CEO: Kan Takase; hereinafter "the Company"), a developer of optical quantum computers, announces its participation in Moonshot Goal 6, "Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050," promoted by the Japan Science and Technology Agency (JST). The Company has joined the research project "Research and Development of Fault-Tolerant All-Optical Quantum Computers."

In this project, where our Director Akira Furusawa serves as the Project Manager (PM), the Company will lead the realization of a fault-tolerant universal quantum computer using the "All-Optical" method, which is a unique technology originated in Japan.

In this project, as the core entity responsible for practical application, the Company is in charge of the integrated design and construction of the entire system—from hardware to software—as well as the research and development of fundamental software.

In conventional optical quantum computers, the processing speed when converting optical signals into electrical signals during measurement was a bottleneck. The Company will establish a method of "All-Optical Feedforward" that processes information as light without converting it into electrical signals, by utilizing Optical Parametric Amplifiers (OPA) and other advanced components. Through this, we aim to realize a global-standard computing environment that achieves both ultra-high-speed processing at a "clock frequency of 10 THz"—10,000 times that of current supercomputers—and ultimate ultra-low energy consumption.

To give shape to this innovative system, we will promote the following two research and development tasks:

1. Research on All-Optical Quantum Computing Systems

We will construct an all-optical computing system that breaks the bandwidth and latency constraints of electrical signal processing. In the initial year (FY2026), we will collaborate with the University of Tokyo, which is responsible for establishing fundamental technology, and the Company will lead the system design with a focus on the scalability required for both future higher clock speeds and large-scale integration. Ultimately, we aim to reach a state where complex large-scale computations can be executed within realistic time and power constraints by achieving integration of 1 million input modes and ultra-high-speed computation.

2. Research on Qubit / Continuous-Variable Conversion Software

Keeping pace with hardware advancements, such as the implementation of error correction functions based on GKP qubits, we will develop a software infrastructure (compilers, SDKs, simulators, etc.) that converts algorithms developed for conventional "qubits" into a format executable on our continuous-variable optical quantum computer.

In the initial year, we will build a foundation for converting circuit representations into machine control parameters for a cloud-based optical quantum computer operated by RIKEN. Our goal is to establish an ecosystem where existing quantum algorithms and circuits developed for qubits can be seamlessly migrated to and utilized on all-optical machines, thereby creating an environment where advanced quantum computation is easily accessible to everyone.

• ‍Fault-Tolerant Quantum Computer: A next-generation quantum computer capable of accurately performing large-scale and complex calculations while self-correcting errors that occur during the computation process.

• ‍All-Optical Quantum Computer: A quantum computer that eliminates the constraints of electrical signals caused by photoelectric conversion and performs the conversion from quantum information to classical information while remaining as light. This enables both an ultra-high-speed clock and large-scale scalability.
