Honda Invests in Quemix to Advance Quantum Computing Applications for Materials Research

Insider Brief

• Quemix has received an investment from Honda Motor to accelerate the development and practical deployment of quantum computing technologies.
• The companies have previously collaborated on quantum computing research, including quantum state readout technology and quantum algorithms for accelerating density functional theory calculations.
• Quemix plans to apply its quantum algorithm technologies to materials development, including research related to next-generation battery materials.

Press release – Quemix Inc. (Head Office: Chuo-ku, Tokyo; President and CEO: Yu-ichiro Matsushita; hereinafter “Quemix“), a company engaged in the research and development of quantum computer algorithms and software, is pleased to announce that it has received an investment from Honda Motor Co., Ltd. (Head Office: Minato-ku, Tokyo; Director, President and Representative Executive Officer: Toshihiro Mibe; hereinafter “Honda”). Through this investment, Quemix will accelerate its efforts to enhance the value of its products and services toward the real-world deployment of quantum computing.

Quemix has worked closely with Honda through joint research using quantum computing, producing a series of pioneering achievements. In May 2025, the companies jointly developed a world-first “new technology for quantum state readout” (*1).  In June 2026, they developed a new quantum algorithm that exponentially accelerates Density Functional Theory (DFT) calculations — a foundational method in computational materials science — on quantum computers (*2).

Building on this investment, Quemix will leverage its advanced quantum algorithm technologies to move quantum technology beyond the theoretical and experimental stages and integrate it fully into practical materials development processes.  Through these efforts, Quemix aims to significantly accelerate the development of next-generation battery materials and other advanced materials.
