Dr. Fujii's Group

The development of basic methods to extract computer performance and R&D on quantum software

The group identifies issues with the quantum advantage in calculations of quantum chemical and physical properties and builds quantum algorithms to solve these issues. In addition, the group derives basic algorithms for quantum machine learning utilizing quantum computing and expands its use to solve issues. As for a methodology, the group employs high-speed simulators using conventional computers to explore the utilization methods of quantum computers expected to appear in the next five to ten years. The group also designs system architectures to utilize the limited functionality of currently existing quantum computers, and performs software research to enhance the performance from quantum devices.

Dr. Le Gall's Group

Research on the theoretical foundations of quantum computing and development of theoretically guaranteed quantum algorithms

The group promotes research on the theory of quantum computing to build the theoretical foundation of the entire project. Specifically, the group theoretically analyzes quantum hardware and software in collaboration with the Osaka University group and the Keio University group. The main goal is to provide theoretical guarantees of quantum advantage for quantum devices and algorithms. The group also develops new computing methods utilizing quantum effects unique to quantum computers (i.e., not effectively simulated by conventional computers), and explores innovative methods to apply quantum computers that should be realized in the next 10–20 years.

Dr. Yamamoto's Group

Develop quantum algorithms geared towards quantum computer applications

The group develops quantum algorithms that should be useful in the very near future. They focus on the utilization of existing quantum computers and work in close collaboration with academia and various industries. After careful examination of diverse issues with partner corporations, the group targets problems in finance, chemistry, and AI. The group also compiles issues in quantum computing and builds theories to reduce hurdles in using them. For example, the group has developed a quantum algorithm for a division method using a parallel multiplier, an information recovery method for statistical processing of the output, and design theory for approximate quantum circuit synthesis.
