Fujitsu and Osaka University Develop Quantum Computing Techniques for Chemical Energy Calculations

Fujitsu and Osaka University have developed new technologies to perform chemical material energy calculations on early fault-tolerant quantum computers, announced in a press release.

The collaboration combines version 3 of Fujitsu’s STAR architecture—a highly efficient phase rotation gate quantum computing system—with a molecular model optimization technique designed to reduce computational resource requirements. These advances make it possible to calculate the energy of complex chemical materials, such as catalyst molecules, within realistic timeframes using early fault-tolerant quantum systems.

According to the partners, previous methods would have required impractical timeframes, extending to millennia, even with earlier versions of the STAR architecture. The new approach is expected to support applications in areas such as drug discovery, ammonia synthesis, and carbon recycling.

Fujitsu and Osaka University plan to continue refining the STAR architecture and optimization technology to expand the practical use of quantum computing in industrial fields, including materials science and finance.
