With the investment, PostScriptum will become a shareholder in SemiQon, a Finnish quantum hardware company building one of Europe’s most ambitious platforms for next-generation quantum technology. The investment will help accelerate the commercialization of SemiQon’s breakthrough technology and support the company’s path toward becoming a leading European quantum hardware company. Finland’s position as a leader in commercial quantum technology receives a major boost from an investment in SemiQon by PostScriptum, the founder’s office led by Peter Sarlin. SemiQon is a world-leading supplier of cryo-optimized electronics for quantum computers. SemiQon has reached a stage where its technology is productized with components now deployed in working quantum systems. SemiQon’s customers include quantum computer manufacturers and system integrators. The silicon chip developed by SemiQon is optimized for operation near absolute zero and is a key component in scaling quantum computers from today’s hundreds of qubits to hundreds of thousands, or even millions, of qubits. This is the level at which quantum computers are expected to surpass classical computers and supercomputers. PostScriptum will provide SemiQon with a strong partner for scaling its commercial operations and accelerating growth. “Quantum computing will define the next era of compute, and the million-qubit era will be powered by developments in control electronics, cooling and other enabling technologies. SemiQon provides cryogenic-ready quantum hardware that enables scalable, affordable, and sustainable quantum computing. Backing SemiQon is one of the most significant bets PostScriptum has made, and we are committed to it for the long term”, says Peter Sarlin, founder and Chairman of PostScriptum. “Finland has become a leading hub for quantum technology research and commercialization in Europe and globally. When we first spoke with Peter, we immediately saw an opportunity to build a new success story around SemiQon’s technology”, says Antti Vasara, Chair of the Board of SemiQon. Ready for industrial scale SemiQon was established in 2023 to continue the commercialization of technology developed by VTT Technical Research Centre of Finland Ltd. After a three-year research phase, SemiQon entered the commercial phase earlier this spring. The silicon-based Cryo-CMOS technology developed by SemiQon is a key platform for moving quantum computers from experimental laboratory systems to commercial products. “This past spring has shown that there is significant interest in our product. Our customers’ trust is based on our ability to deliver top-quality components, and we are not tied to a single approach to building quantum computers. Our support for multiple quantum computing modalities is a significant advantage as we build critical enabling technologies for the future and strengthen Europe’s position in the global quantum industry,” says Himadri Majumdar, Co-Founder and CEO of SemiQon. The cryo-optimized CMOS platform is designed and manufactured in line with existing standards for silicon-based semiconductors. It can be produced at industrial scale using the same methods and equipment as today’s silicon microchips. The company designs and manufactures its products in Otaniemi, Espoo. “Our goal is to make SemiQon the world’s leading enabling technology provider in quantum. What Peter and the team bring, expertise, networks, vision, is exactly the capital that matters most at this stage.” Majumdar continues. What is Cryo-CMOS? It addresses a major bottleneck in scaling quantum computers by bringing the quantum processors readout and control electronics closer to the processor itself. The electronics must operate at temperatures close to absolute zero without interfering with the qubits. By enabling control and readout inside the cryostat, the technology can significantly reduce the wiring infrastructure currently required between the quantum processor and room-temperature electronics. This is a prerequisite for scaling quantum computers into commercially viable systems. Cryo-CMOS is compatible with existing semiconductor design and manufacturing standards and can be produced using established silicon chip manufacturing methods. Beyond quantum computing, the applications of SemiQon’s Cryo-CMOS technology extend to other critical industries such as space technologies and high-performance computing. About SemiQon SemiQon’s mission is to realize the promise of quantum computing by delivering scalability through powerful, resilient, and cost-effective silicon-based quantum hardware. Its technology builds upon decades of development and know-how from the semiconductor industry, making its cryo-optimized CMOS electronics commercially competitive and well-suited for mass-manufacturing. SemiQon’s first-in-the-world cryo-optimized CMOS delivers scalability and power efficiency to wide-ranging applications in quantum, space, and beyond.

The UK Ministry of Defence has released its new Defence Investment Plan (DIP), establishing a clear shift in how the military intends to procure, scale, and deploy emerging technologies. For the quantum ecosystem, this document marks a critical transition: quantum is moving decisively out of experimental labs and directly into defence procurement pipelines. The Strategic Framework At the core of this strategy is a £1.6 billion commitment to UK Defence Innovation (UKDI) (approx. €1.85B) over the next four years. Crucially, this funding targets “dual-use” technologies. The UK Ministry of Defence (MOD) recognizes that building a resilient quantum supply chain requires deep integration with commercial industry, rather than relying on isolated defence-specific R&D. For industry leaders, system integrators, and deep-tech startups, the plan highlights three primary areas where quantum capabilities are being fast-tracked into frontline deployment: Sovereign Navigation & Alternative PNT: Electronic warfare and satellite jamming have made GPS vulnerability a top operational risk. The DIP explicitly prioritizes quantum sensing and atomic clocks to enable precise, un-jammable navigation across contested environments—reducing reliance on space-based assets. Hardening the Digital Backbone: With the long-term cryptographic risks posed by quantum computing developments, the MOD is prioritizing the immediate integration of quantum-resistant cryptography into command-and-control networks to secure communications against future intercept-now, decrypt-later tactics. Multi-Domain Hardware Integration: Quantum systems are no longer treated as standalone projects. The investment plan mandates integrating these technologies into high-priority platforms, including the Navy, Combat Air and intelligence. The Industrial Outlook For the quantum industry, the message is clear: the defence sector is shifting its focus from basic scientific discovery to engineering, manufacturing, and high-TRL (Technology Readiness Level) deployment. To participate in these procurement pipelines, companies must comply with national security regulations and demonstrate clear pathways toward European and allied technological sovereignty. QBN Members Briefing The briefing paper analysing the specific sub-systems, procurement timelines, and supply chain implications of the UK Defence Investment Plan is available for you to read directly in the private Member Area. QBN WG Quantum Technologies for Defence & Security The QBN Working Group Quantum Technologies for Defence & Security (WG QDS) serves as the strategic bridge between deep-tech innovators, ministries of defence, and military stakeholders. Backed by a powerful network of over 70 quantum vendors and defence primes, alongside 20+ public institutions and international MoDs, we help dual-use quantum companies navigate complex regulations. Together, we translate high-level defence policy into actionable steps, lower compliance and integration barriers for SMEs, design clear product-to-capability roadmaps, and facilitate high-trust ecosystem matchmaking.

Munich, Germany – July 1, 2026 – The Quantum Business Network (QBN) has officially issued a comprehensive position paper in response to the newly released “Quantum Technologies Roadmap” (Version 1.0, May 2026) under Germany’s High-Tech Agenda Germany (HTAD). Recognizing the roadmap as a significant programmatic step forward, QBN is calling on federal ministries and decision-makers to rapidly transition the strategy from a research-centric plan into a high-execution, market-driven industrial implementation agenda. Last week, QBN officially handed over the position paper to leadership at several key federal ministries, including the Federal Ministry for Research, Technology and Space (BMFTR), the Federal Ministry for Digital Transformation and Government Modernisation (BMDS), the Federal Ministry for Economic Affairs and Energy (BMWE), and the Federal Ministry of Defence (BMVg). The paper outlines a clear consensus from the German quantum industry: while the roadmap establishes valuable, measurable milestones and correctly prioritizes technology transfer and pilot lines, a critical gap remains regarding operational agility, supply chain security, and commercial viability. Addressing Operational Shortfalls and Strategic Risks A structured consultation conducted by QBN across its network revealed that a striking 70% of surveyed quantum companies already face operational or strategic risks due to systemic gaps in the current framework. Chief among these concerns are slow and bureaucratic funding procedures – which contrast sharply with the agile, rapid-turnaround funding models utilized in competing markets like the USA, Singapore, and China. Furthermore, 60% of companies are currently exploring growth capital options or corporate structures outside of Europe due to a severe shortage of domestic scale-up financing, while 43% report critical dependencies on non-European suppliers for foundational components and enabling technologies. Six Industrial Priorities for Germany’s Quantum Economy To safeguard technological sovereignty and protect future domestic value creation, the QBN position paper urges the federal government to refine the roadmap across six core action areas: Translate the Roadmap into an Implementation Agenda Launch a Dedicated Funding Line for Enabling Technologies Drive Mission-Oriented Public Procurement Accelerate Funding & Mobilize Growth Capital Focus on Steering Industrial Use Cases Align the Talent Agenda with Industrial Competencies A Long Tradition of Trusted Ecosystem Advocacy This position paper builds upon QBN’s long-standing tradition of bridging the gap between industry, science, and public policy. Following its appointment as an official partner of Germany’s High-Tech Agenda Digital (HTAD), QBN has consistently driven industrial alignment. The current paper acts as a direct continuation of QBN’s continuous contributions, which include the industry workshop of December 2025, a subsequent position paper that directly informed the government’s roadmap drafting process, and an ongoing strategic dialogue with the BMFTR and other federal entities to align funding frameworks with commercial realities. “Research funding remains necessary, but it is no longer sufficient on its own,” stated Johannes Verst, CEO of QBN. “For Germany and Europe to secure a competitive quantum economy, the focus must shift rapidly to productization, robust supply chains, and active market creation before it is too late and we lose another industrial revolution. QBN and its members stand fully ready to co-design and accelerate this implementation phase.” About QBN QBN is the global industrial network for quantum technologies, dedicated to fostering commercialization, cross-sector collaboration, and structured dialogue between industry, academia, and political stakeholders.

Standing alongside long-term partners and friends like the PTB, the collaborative project QR.N and other key deeptech players is both a great honour and a significant validation of our work. Shaping Policy with Industry Reality For more than six years, QBN has provided a strong, unified voice for the quantum industry. This recognition from the German Government underscores the vital role the commercial ecosystem plays in national strategy, technological sovereignty and economic competitiveness. A national roadmap only works if it aligns with the real-world challenges faced by startups, corporations, end-users and investors. Over the past year, QBN has actively worked to ensure these commercial realities are baked into the HTAD Quantum Technologies Roadmap: Turning Targets into Action The success of the High-Tech Agenda won’t be measured by the document itself, but by how effectively government and industry collaborate to execute these targets and challenge the status quo. Since our inception, QBN has supported the German Government, the European Commission, and national governments across Europe to build a resilient, thriving quantum economy. We look forward to continuing this work, ensuring that Germany and Europe remain premier hubs for quantum innovation and commercialisation. Thank you to BMFTR, BMWE and BMVg for the great collaboration. Thank you to our members and partners who make this advocacy possible. Let’s further shape the conditions in which we are building the quantum economy!
