Announcement summary The two companies have been conducting joint research on materials calculations using quantum computers to reduce the trial-and-error, time, and cost associated with materials development.

Under the new tie-up, they will strengthen the structure for joint research, and Mitsui Kinzoku will take a capital stake in Quemix through its CVC fund. Quemix is a consolidated subsidiary of TerraSky and conducts R&D on quantum computers, quantum sensors, and materials calculations. The company developed a quantum-chemical calculation algorithm for fault-tolerant quantum computers called probabilistic imaginary-time evolution (PITE) and has obtained domestic patent rights. Quemix aims to realize practical use of quantum computers in the field of materials calculation and simulation by 2030. Key points • The agreement date for the capital and business alliance was July 17, 2026, and it was announced on August 3, 2026. • Mitsui Kinzoku will subscribe to Quemix’s third-party allotment of new shares through a 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 toward commercialization have not been disclosed. Technical and business significance From a technical perspective, the significance lies in strengthening the link between Quemix’s quantum-chemical calculation algorithms and Mitsui Kinzoku’s materials development capabilities, creating a structure to translate research outcomes into practical materials simulation. From a business perspective, building a capital relationship in addition to joint research expands the foundation for sustained R&D. However, because the target materials, performance goals, and investment terms have not been disclosed, the impact on commercialization must be assessed based on future results. What to watch next Going forward, attention will focus on whether the target materials and development milestones for the joint research are concretized. In subsequent research outputs, calculation accuracy and computation time compared with conventional methods, and the practical applicability to materials development will be important evaluation criteria. It will also be important to see 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 per se, 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 reveal the depth of the relationship or the parties’ commitment. What gives this announcement weight is that Mitsui Kinzoku has become a shareholder of Quemix, aligning their interests. That said, the press release does not disclose the investment amount or share ratio, so it is not yet possible to judge how serious the investment is; it could be merely a symbolic strategic investment. When evaluating this news, it is more important to see whether actual materials development projects and commercial cases emerge from the relationship than to focus solely on the capital tie-up itself.

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.
