Mitsui Kinzoku will subscribe to Quemix’s third-party allotment through its CVC fund, and the two companies will continue their joint research. Summary of Announcement The two companies have been advancing joint research on materials calculations using quantum computers to reduce the trial-and-error, time, and cost associated with materials development. The results of that research were published on June 1, 2026. Under the new alliance, the joint research framework will be strengthened and Mitsui Kinzoku will take an equity stake in Quemix through its CVC fund. Quemix is a consolidated subsidiary of Terrasky and engages in R&D related to quantum computers, quantum sensors, and materials calculations. It has developed a quantum chemistry algorithm for error-tolerant quantum computers called the probabilistic imaginary time evolution (PITE) method, and holds domestic patent rights. The company is targeting 2030 for the practical application of quantum computers in the materials calculation and simulation domain. Key points • The date the capital and business alliance was concluded was July 17, 2026, and it was announced on August 3. • Mitsui Kinzoku will subscribe to Quemix’s third-party allotment through its CVC fund. • The two companies published the results of their joint research on materials calculations using quantum computers on June 1, 2026. • The investment amount, share ratio, target materials, and specific steps to commercialization have not been disclosed. Technical and Business Implications On the technical side, the significance lies in strengthening the framework that links Quemix’s quantum chemistry calculation algorithms with Mitsui Kinzoku’s materials development, aiming to convert research outcomes into practical materials simulations. From a business perspective, building an equity relationship in addition to joint research can be seen as an effort to expand the foundation for sustained R&D. However, the target materials, performance goals, and investment conditions have not been disclosed, so the effect on commercialization must be evaluated based on future results. Points to Watch Going forward, the focus will be whether the target materials and development process of the joint research are specified. In the next research results, comparison of calculation accuracy and computation time with conventional methods, and the scope of applicability to actual materials development will be important factors for judgment. It will also be worth watching whether the investment amount, share ratio, and intermediate milestones toward the 2030 commercialization target are disclosed. ✍️ Quantum Index Analysis The essence of this announcement is not fundraising, but that a materials manufacturer has put risk capital into a quantum algorithm company. “Joint research” is a common phrase in press releases about quantum computers, but joint research alone does not necessarily reveal the depth of the relationship or the level of commitment between companies. What gives this announcement significance is that Mitsui Kinzoku has become a shareholder in Quemix and thus shares aligned interests. That said, the press release does not disclose the investment amount or share ratio, so it is not possible at this point to judge the seriousness of the investment. It could be merely a symbolic strategic investment. In evaluating this news, it is more important to determine whether actual materials development projects and commercial examples emerge from this relationship than the capital partnership itself. Moreover, the success or failure will not be decided by Quemix and Mitsui Kinzoku alone. Because it will be greatly affected by the timing and performance improvements of FTQC, full-scale commercialization of materials simulation as a business requires progress in both software and hardware.

Do not give a high rating to summaries, paraphrases, explanations of technical terms, or generic observations such as "this will be worth watching" or "the timeline remains uncertain" if they could easily be produced by a general-purpose generative AI, even if they are well written. Use the following five-level rating scale. * **S — Advanced Original Expert Analysis**: Integrates multiple sources, comparisons, industry knowledge, or other information to provide important insights, evaluations, or a broader picture that would be difficult to obtain simply by reading the original sources individually * **A — Subject-Specific Expert Analysis**: Contains clear comparisons, reasoning, verification, or evaluation specific to the company, technology, or announcement being discussed * **B — Mainly Expert Explanation**: Provides specialist explanation or organization of the topic, but contains limited original analysis specific to the subject * **C — Organization and Summary of Primary Information**: Primarily summarizes primary information, but provides some added value through human editing, organization, or supplementary explanation * **D — AI-Level Summary and Formatting**: Offers little beyond the summarization and formatting of primary information that could be produced by a general-purpose generative AI, with almost no original analysis or informational value **Original reporting, proprietary data, original calculations, or the discovery of new facts are not required for an S rating.** An article may qualify for S if it compares and integrates multiple publicly available sources to provide important insights or a broader picture that readers could not easily obtain by reading those sources individually. However, do not give an S rating merely because the article contains a large amount of information, covers many subjects, or uses extensive technical terminology. In particular, consider the following points. * Does the article contain information or perspectives that would be difficult to obtain simply by reading the original announcement? * Does it contain comparisons, reasoning, verification, or evaluation specific to the subject? * Does it integrate multiple pieces of information to provide a new understanding or broader picture? * Could the content easily be produced by a general-purpose generative AI? * Are you avoiding giving a high rating merely because the article uses technical terminology or headings such as "Analysis" or "Key Points"? In your response, first briefly show the **S–D rating scale above**, and then clearly indicate **where this article falls within that scale**. Then briefly explain the following. * **Rating for this article: S / A / B / C / D** * **Reason for the rating** * **Specific passages that qualify as original analysis** If you are uncertain between two ratings, choose the lower one rather than the higher one.
