Build mathematical models faster. JijModeling 2 v2.6 and v2.7 are now available. https://lnkd.in/gyGba4WF JijModeling 2 is JIJ’s next-generation modeling tool for mathematical optimization, offering stronger type safety, greater expressive power, and improved usability for real-world applications. The latest releases introduce: 🟦 Faster compilation — a new Flat AST–based compiler architecture brings compilation speed and memory efficiency on par with or better than JijModeling 1 🟦 Easier debugging — clearer, more specific error messages, supported by a comprehensive Error Code Index documenting error causes and recommended solutions These improvements are expected to shorten the iteration cycle for large-scale models and LLM-assisted workflows, helping optimization practitioners and R&D teams move more quickly from formulation and validation to practical use. 🔗 Docs: https://lnkd.in/gMav3yhD 🔗 Discord Community: https://lnkd.in/gVmaxzwn #JijModeling #MathematicalOptimization

When optimization problems become large and highly constrained, finding a feasible solution within the available time can be a challenge in itself. JIJ has launched JijZept Solver v4 beta, featuring redesigned search capabilities to help find feasible, high-quality solutions more reliably for complex production planning, logistics, and scheduling problems. Now available to existing JijZept users and selected early-access partners. Learn more about the update: https://lnkd.in/gGA6njQP Explore JijZept Solver through our free API tier: https://lnkd.in/ghaxQkzD #MathematicalOptimization #OperationsResearch #JijZept

We’re pleased to announce that JIJ has raised JPY 840 million, approximately US$5.2 million, in equity financing led by Global Brain Corporation. This financing marks the next phase of JIJ’s growth as we expand enterprise adoption of mathematical optimization, advance our AI-enabled optimization platform and quantum software capabilities, and scale our business globally. We’re grateful to our investors, customers, partners, and team for their continued support as we work to bring advanced optimization technologies into wider use across industries.

One quantum program. Estimate its cost, then run it on any backend. Qamomile v0.14.0 is now available. Qamomile is JIJ's open-source, Python-based quantum programming language. As quantum hardware advances, more algorithm development is moving onto real devices, which makes both running on hardware and estimating the qubits and gates an algorithm needs increasingly important. Today, though, the two are typically handled with different tools. We are developing Qamomile to tackle these needs. With Qamomile, you can: ・Write Pythonic quantum code — a type system that catches invalid operations early and suggests fixes, plus native Python if/while driven by measurement results ・Call built-in algorithms — ready-made subroutines like QSVT (quantum singular value transformation) instead of reimplementing common patterns ・Estimate resources before you run — qubit and gate counts computed algebraically from a single program, so you see how they grow as the problem scales ・Write once, run anywhere — one program across multiple SDKs, including Qiskit and CUDA-Q, and intermediate representations, with no separate estimation and execution circuits to maintain. This release is another step toward user-friendly quantum algorithm development for both today's quantum devices and future fault-tolerant quantum computing. Qamomile is open source and available now: pip install -U qamomile Read the announcement: https://lnkd.in/gxyn98pk Explore Qamomile: https://lnkd.in/gM_dEMpY

The Global Quantum Forum highlighted the importance of international collaboration in advancing quantum technologies. Thank you to Quantum STrategic industry Alliance for Revolution(Q-STAR) and JETRO - Collaborate & Invest Japan for bringing together the global quantum community. We look forward to strengthening partnerships between the U.S. and Japan and helping bring quantum solutions into practice.
