Key points • Amplify Quantum 1.3 adds OqtopusClient with OQTOPUS support • By changing the solver specification, existing Amplify SDK code can use System F • System F currently provides 64 physical qubits and is designed to be expandable to 256 physical qubits • The same optimization problem can be run and compared across multiple quantum and classical backends Technical and business implications Technically, the update separates problem description code from the target hardware, making it easier to switch between quantum and classical solvers. Users can add domestic superconducting quantum computers to their comparison and validation workflows without extensive code rewrites. From a business perspective, this expands access paths to domestic compute resources on ABCI‑Q and could facilitate exploration of use cases in quantum‑HPC hybrid environments. The announcement does not, however, specify concrete solver performance, pricing, commercial‑use conditions, or the full scope of availability. What to watch Key future indicators will include comparative solution quality, processing time, and problem sizes achievable when System F is evaluated against other quantum and classical solvers on identical problems. It will also be important to see how ABCI‑Q's eligibility, pricing, and commercial‑use terms are clarified, and whether real-world adoption examples are published. Monitor progress toward the planned expansion to 256 physical qubits and how that affects the practicality of optimization workloads. ✍️ Quantum Index Analysis Fixstars Amplify's strength is not only the number of quantum backends it supports. Its in‑house quantum‑inspired solver already delivers high performance suitable for practical use, while the product steadily broadens future options including gate‑based quantum hardware. While many quantum companies remain at the stage of proof‑of‑concepts or roadmap announcements, Fixstars Amplify has multiple user‑published domestic deployment examples in addition to its own announcements. Covering the spectrum from foundational research to production use in a single product, and enabling customers to move beyond “we tried quantum” to actual business use, gives the company a meaningful lead over many peers. Support for System F does not immediately create a decisive advantage.

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.
