Hamburg, Germany — 26 May 2026 — JIJ Inc. (Headquartered in Minato-ku, Tokyo; CEO: Yu Yamashiro), a provider of quantum technology and optimisation software, today announced the establishment of its first entity in the European Union, JIJ EU (JIJ GmbH), in Hamburg, Germany. Located within the DLR Quantum Computing Initiative’s (DLR QCI) Innovation Center, the new entity marks a major step in JIJ’s European expansion and provides a local base for advancing industrial quantum optimisation applications across the region.Advancing Industrial Quantum Optimisation in EuropeJIJ develops optimisation software designed to make quantum computing applicable to real-world industrial challenges. Its flagship platform, JijZept, enables engineers and domain experts to model and solve combinatorial optimisation problems — complex decision-making challenges involving large numbers of variables and constraints.Already applied in areas such as energy dispatch optimisation, industrial scheduling, and supply chain management, JijZept helps accelerate the development of practical optimisation solutions through intuitive mathematical modelling rather than low-level quantum programming.Building on this foundation, JIJ’s expansion into Hamburg places the company closer to Europe’s quantum computing ecosystem, including DLR QCI and European initiatives such as Q-NEKO (Nippon-Europe Quantum Kollaboration ).Q-NEKO is an EU–Japan initiative aimed at developing hybrid quantum–classical computing frameworks that combine high-performance computing (HPC) with quantum systems. Within this framework, JIJ contributes to the design and validation of quantum-enhanced optimisation workflows for industrial applications, including problem formulation, decomposition, and benchmarking, alongside DLR and other European stakeholders.JIJ and DLR researchers have also co-authored recent academic work. On 4 May 2026, researchers from JIJ and DLR published “Geometric Quantum Physics-Informed Neural Network”, a paper introducing a quantum machine learning approach that embeds the geometric structure and symmetries of physical systems directly into quantum circuit design. The method aims to improve accuracy and parameter efficiency when solving partial differential equations, which are fundamental to engineering, simulation, and industrial optimisation.Together, these activities demonstrate JIJ’s growing role in Europe’s quantum computing ecosystem. The establishment of JIJ EU within the DLR QCI Innovation Center provides a local base for technical exchange, ecosystem engagement, and the development of application-oriented quantum optimisation technologies.European Expansion and Industrial Deployment StrategyWith the establishment of JIJ EU in Hamburg, JIJ is strengthening its presence in Europe and positioning itself closer to industrial users, research institutions, and technology partners working on application-driven quantum computing. A key focus of JIJ EU will be the exploration of hybrid HPC–quantum computing environments. Building on experience from initiatives such as Q-NEKO, JIJ aims to advance workflows that combine classical high-performance computing with quantum technologies, with the goal of supporting scalable and practical approaches to industrial optimisation problems.JIJ will also work with regional partners in Hamburg to apply its optimisation technology to real-world use cases in logistics, manufacturing, port operations, and energy systems. These sectors involve complex scheduling, resource allocation, and operational planning challenges that are well suited to advanced optimisation.In this context, JIJ EU will serve as an industry-level bridge between Japan and Germany, helping connect research capabilities with practical industrial applications in quantum and advanced computing.The Hamburg base will support the advancement of quantum-enhanced optimisation technologies and help accelerate their deployment in real-world industrial applications.Executive CommentsYu Yamashiro, CEO, JIJ Inc., said:“Germany has long been at the frontier of both scientific research and industrial application — precisely the combination that quantum optimisation needs to deliver real impact. Establishing JIJ EU in Hamburg is not merely a geographic expansion, but a long-term commitment to engaging with European researchers, industries, and institutions.”Robert Axmann, Head DLR Quantum Computing Initiative, said:“With our Innovation Centers, we are creating a strong ecosystem to enable sovereign and competitive quantum computing for research, industry and the public sector. With JIJ aboard, we are not only strengthening this ecosystem, but also our vibrant and impactful community in Hamburg.” Alois Krtil, CEO of ARIC and Hamburg Quantum Innovation Capital (hqic), said:“Hamburg plays a pivotal role in the field of quantum computing hardware based on ion traps and neutral atoms, and is a leader in industrial applications within aviation, life sciences, and logistics. JIJ EU strengthens this ecosystem by bringing advanced expertise in quantum optimisation software.”Nina Alswede, Key Account Manager Research & Innovation, Hamburg Invest, said:“Hamburg continues to position itself as a leading European hub for quantum technologies. The establishment of JIJ EU reflects the city’s attractiveness for international deep-tech companies.”Aresa Brand, Deputy Director International Investments, Hamburg Invest, added:“JIJ’s expansion into Hamburg further strengthens our well-established Japanese business community of around 100 companies. As part of Hamburg’s international ecosystem, JIJ will help deepen cooperation between Japanese and European innovation partners.”About the DLR Quantum Computing Initiative (DLR QCI)The DLR Quantum Computing Initiative create a strong ecosystem for sovereign and competitive quantum computing in Germany and Europe.
