Die USA machen Ernst. Mit den am 22. Juni 2026 unterzeichneten Executive Orders (EOs) 14413 und 14409 treiben sie den Marktaufbau und die Post-Quanten-Migration mit enormer Geschwindigkeit voran. Quantentechnologien sind dort längst kein reines Forschungsthema mehr, sondern werden konsequent als strategische Infrastruktur und Frage der nationalen Sicherheit behandelt. In Europa drohen wir derweil, den Anschluss zu verlieren. Während wir uns in kleinteiliger Grundlagenförderung und bürokratischer Trägheit verlieren, gerät unser Ökosystem massiv unter Druck. Unser jüngstes QBN-Positionspapier zeichnet ein alarmierendes Bild direkt aus der industriellen Praxis: 60 % der europäischen Quantenunternehmen prüfen derzeit aktiv Finanzierungsoptionen außerhalb Europas. 43 % der Unternehmen hängen existenziell von außereuropäischen Komponenten ab. 70 % der Akteure sehen akute operative Risiken für ihr Geschäft am Standort. Wir stehen vor einer historischen Weichenstellung. Um eine schleichende Abwanderung unserer Schlüsselindustrien zu verhindern, fordert QBN einen radikalen Paradigmenwechsel im deutschen und europäischen Förder- und Beschaffungsmodell. Die 4 Kern-Handlungsfelder für den Standort 1. Tempo & Kapital: Agilität statt Bürokratie Lange, unvorhersehbare Entscheidungszyklen lähmen unsere Innovationskraft. Wir fordern die Einführung von schnellen 3-Monats-Förderentscheidungen für strategische Deep-Tech-Projekte sowie staatlich unterstützte Deeptech-Matching-Fonds, um privates Wachstumskapital zu mobilisieren. Anstelle von reinen Zuschüssen müssen unbürokratische Eigenkapitalbeteiligungen an etablierten Playern die Regel werden. 2. Marktlogik: Der Staat als Ankerkunde Das Gießkannenprinzip hilft uns nicht weiter. Es nützt dem Standort wenig, Dutzende Startups mit Kleinstbeträgen zu subventionieren, wenn am Ende keine echten Aufträge entstehen. Der Staat muss als Ankerkunde (Anchor Customer) auftreten. Wir brauchen beschleunigte öffentliche Ausschreibungen für reale Quantenhardware an HPC-Zentren und eine gezielte Einbindung des Dual-Use- und Verteidigungssektors. 3. Souveränität bei Hardware & Lieferketten Die extreme Abhängigkeit von außereuropäischen Komponenten macht uns anfällig für geopolitische Blockaden. Wenn europäische Lösungen preislich und zeitlich nicht wettbewerbsfähig sind, weichen Akteure auf Drittstaaten aus – wie die jüngste Entscheidung der Universität Malaga zeigt, einen chinesischen Quantencomputer zu installieren. Wir müssen europäische Lieferketten für Schlüsselkomponenten absichern, strenge Souveränitäts-Klauseln für geförderte IP einführen und konsequent technologieoffen bleiben. 4. Außenwirtschaft, Exportkontrolle & Flankierung vor Ort Quantentechnologie ist ein politischer Markt. Während andere Nationen ihre KMUs bei Auslandsmessen auf Botschaftsebene und durch hochkarätige diplomatische Empfänge unterstützen, kämpfen deutsche Unternehmen oft auf sich allein gestellt. Die Außenwirtschaftsförderung im Deep-Tech-Sektor muss zur Chefsache der Auslandsvertretungen werden. Zudem muss das BAFA in die Lage versetzt werden, transparente und fördernde Unterstützung bei Exportkontrollen zu leisten. Der unterschätzte Hebel: Die PQC-Migration Wir dürfen die Hardwarerivalität (EO 14411) nicht isoliert von der Post-Quanten-Migration (EO 14409) betrachten. Die PQC-Umstellung schafft überhaupt erst den Markt, den neue Hardwaretechnologien bedienen. Richtlinie vs. Budget: Das BSI setzt zwar richtige Fristen für 2030 und 2032, doch ohne gekoppelte, milliardenschwere Beschaffungsoffensiven des Staates entstehen keine Märkte. Wir brauchen dedizierte Sonderbudgets für den öffentlichen Sektor. Kryptographische Souveränität: Das BSI fordert zu Recht hybride Migrationspfade, während die USA auf reine PQC-Lösungen drängen. Wenn wir heimische Anbieter jetzt nicht durch staatliche Aufträge stärken, zwingt der US-Sog unsere Dienstleister zur Anpassung – und wir verlieren die Kontrolle über unsere Verschlüsselungsstandards. Partnerschaft auf Augenhöhe statt passiver Rolle QBN bekennt sich ausdrücklich zur transatlantischen Zusammenarbeit. Mit unseren strategischen Brückenköpfen bauen wir die notwendigen kommerziellen Kanäle zu unseren internationalen Partnern auf. Kooperation darf für Europa jedoch nicht bedeuten, sich passiv in fremde Lieferketten einzufügen oder ausländische Standards ungefiltert zu übernehmen. Wir müssen diese Partnerschaft aktiv, selbstbewusst und im Sinne unserer eigenen Interessen mitgestalten. Nur wenn wir internationale Zusammenarbeit und den Schutz europäischer IP konsequent zusammendenken, bleibt Europa ein souveräner Partner auf Augenhöhe – anstatt zum bloßen Talent-Inkubator und Technologie-Importeur zu werden.

Last week, the Quantum Business Network (QBN) partnered in the inaugural Servus Scale Up 2026 – The Bavarian-French Startup Festival. Co-organized by La French Tech Munich and co-hosted by the IHK für München und Oberbayern, the event brought together startups, investors, researchers, and policymakers from France and Germany with a singular, practical focus: turning Europe’s scientific quantum research into commercial market success. The QBN ecosystem was strongly represented throughout the program, showcasing our members’ leadership across quantum computing, industrial applications, and enabling technologies: Scaling Europe’s Quantum Future: Prof. Jeanette Lorenz (Head of Department at Fraunhofer IKS) and Prof. Thomas Volz (General Manager at Quandela) joined the expert panels to share practical strategies for scaling technology and building resilient, cross-border supply chains. Securing Technological Sovereignty: Dr. Laurent Guiraud (CEO and Co-Founder of ColibriTD) contributed to discussions on building trusted, reliable partnerships between deep-tech developers and industrial end-users. Award-Winning Innovation: QBN member Peak Quantum received the Best German Startup Award during the pitch competition, highlighting the high-caliber talent emerging within our network. Practical Takeaways for the Quantum Industry & Policy The panel discussions and bilateral exchanges pointed to four core actions required to move the European quantum sector forward: Move from Lab to Market: Europe has world-class scientific research, but lags behind in commercialization. To scale, the ecosystem must focus on market demand, competitive business models, and faster industrial adoption. Support the Whole Value Chain: True technological independence is not just about building quantum hardware. European sovereignty requires active, local development in software, enabling components (like lasers and cryogenics), and secure intellectual property. Implement “Co-Design” Workflows: Rather than building technology in a vacuum, quantum hardware and software providers must design their systems in direct coordination with industrial end-users to solve specific, real-world calculations. Leverage Cross-Border Supply Chains: The French and German quantum ecosystems complement each other. Connecting these hubs directly is the fastest way to build a reliable, European-made supply chain that can compete globally. Ultimately, the event proved that the technological foundations in Europe are incredibly strong. However, winning a global market share will depend entirely on how fast we can get industrial companies to adopt these technologies and how closely we can collaborate across borders. QBN remains committed to serving as the central network that bridges the gap between research, investment, policy, and industry deployment. A sincere thank you to La French Tech Munich for organizing Servus Scale Up 2026, IHK für München und Oberbayern for co-hosting, and our fellow ecosystem partners Quantum Launchpad, TUM Venture Labs, Le Lab Quantique, Bayern Innovativ, and Fraunhofer AHEAD for making this valuable bilateral exchange possible.

SMEs often view quantum technologies such as quantum computing as a distant science fiction concept, but the race to integrate it into supply chains and logistics is already happening. So the key question is: What problems can quantum technologies actually solve for my company? Or how can our company supply the emerging quantum industry? This was at the centre of the panel discussion “Quantum for SMEs & Family-Owned Companies”, organised by ALPHAZIRKEL and hosted by UnternehmerTUM, where QBN CEO Johannes Verst together with QBN member 42de GmbH joined managing directors and investors to discuss when and how small and medium-sized companies (SMEs) should approach the hyped topic “quantum”. The addressable quantum market is projected to reach €9 billion by 2030, while quantum technologies are expected to generate up to €800 billion in global economic value by 2040. These figures underline why more and more businesses are beginning to assess potential risks and opportunities, means what position they can aim to benefit as a supplier and where quantum could help tackle technical or operational pain points. Why SMEs Should Act Today Preparing for quantum does not require major investments or immediate access to specialised hardware. Instead, the next 12 months should be defined by identifying where technology can solve real technological or business challenges. However, navigating this landscape can be complex. As the central industry network in Germany, QBN acts as a single point of contact, bridging the gap by connecting businesses directly with member organisations that possess the specialised software, hardware, and integration expertise required to launch e.g. pilot projects. The User Perspective: The Learning Curve Starts Today Future quantum applications in logistics, manufacturing, scheduling, simulation and materials development will require far more than purchasing software once it becomes commercially available. Integrating quantum into business processes starts with understanding your own data, workflows and optimisation challenges. The learning curve is steep, making early preparation a strategic advantage rather than a technological exercise. 2. The Supplier Perspective: Value Chains Are Being Built Now From lasers and cryogenic systems to control electronics and enabling technologies, global quantum supply chains are taking shape today. Strategic partnerships are already being established, creating long-term opportunities for companies that engage early rather than trying to catch up later. 3. The Security Perspective: “Store Now, Decrypt Later” Is a Real Threat Quantum computers will eventually break today’s encryption methods. Adversaries are already stealing sensitive company data and intellectual property to decrypt it once sufficiently powerful quantum computers become available. Beginning the transition to Post-Quantum Cryptography should therefore become part of every organisation’s long-term cybersecurity strategy. How Can SMEs Get Started? Preparing for quantum does not require major investments or immediate access to specialised hardware. For most businesses, the next 12 months will be defined by how quickly they begin understanding where quantum can create value within their own organisation. A practical starting point is to: Pinpoint your most complex optimization, scheduling, simulation or other computational challenges before looking at the technology. Instead of searching the market, leverage the QBN network to tap into members with proven capabilities in quantum software development, hardware access, and systems integration. Collaborate with specialized ecosystem partners to design highly targeted pilot projects, using cloud-based access to test applications without heavy upfront infrastructure costs. The Competitive Advantage Starts Today The companies that will benefit most from quantum will not necessarily be those investing the most capital today, but those building the strongest strategic readiness. As Germany’s central quantum industry network, QBN serves as the one-stop shop for businesses entering the quantum economy, simplifying navigation, matching business needs to technical solutions, and fostering cross-industry collaboration. Through this collaborative ecosystem, SMEs gain direct, frictionless access to the cutting-edge capabilities of QBN members, who provide the practical expertise, technology, and integration power to turn theoretical quantum advantage into real-world business value. Quantum readiness begins with knowing which technological and business problems you cannot afford to ignore, and knowing the ecosystem that can help you solve them.

Aqarios goes public: Germany’s first publicly listed quantum computing company Munich, 14 July 2026 – Aqarios GmbH has gone public through a SPAC transaction with Fonterelli SPAC 4 AG. Aqarios GmbH is known as one of the leading European providers of application-oriented quantum software for optimizing complex industrial problems. With today’s entry of the contribution in kind into the commercial register, Aqarios GmbH is now a wholly owned subsidiary of Fonterelli SPAC 4 AG, which will operate from now on as Aqarios Quantum Technologies AG. With this transaction, the company is, to our knowledge, the first publicly listed pure-play in quantum computing on a German stock exchange. The shares are traded on the Düsseldorf Stock Exchange. A spin-off from cutting-edge research at LMU Munich Aqarios GmbH (“Aqarios”) was founded in 2021 as a spin-off from Ludwig-Maximilians-Universität München (LMU). At the core of its business is the development of software for optimizing complex problems – from supply chains and energy grids to production plans and investment portfolios. To this end, Aqarios GmbH has developed advanced solutions and, in particular, software based on quantum computing. Already today, Aqarios can point to successful projects with well-known DAX corporations and leading industrial companies such as BASF, E.ON and MTU Aero Engines. Since its founding, Aqarios has built a proprietary technology platform, won renowned industry and technology partners, and established itself in publicly funded cutting-edge research projects. The company operates across industries in the energy, finance, logistics, aviation and manufacturing sectors. Luna: making quantum computing usable At the core of the business is the proprietary Luna platform. Luna makes the performance of quantum computers practically usable for companies – without requiring them to build up their own quantum expertise. The platform provides the necessary software and the appropriate algorithms, so that optimization tasks such as supply-chain, energy-grid or logistics optimization can be solved with the help of quantum computing. Users can thus focus entirely on the questions within their own field of expertise. The decisive factor here is the hardware-agnostic approach: Aqarios’ customers are not tied to any single hardware manufacturer and can access a wide range of different quantum computers through Luna. In addition, Luna combines classical and quantum-based computing, so that the best available technology is used for each problem. Real-world problems can already be solved this way today, and customers do not have to commit to a single technology prematurely. The innovative strength of Aqarios and the Luna platform has received multiple awards, including the Quantum Effects Award 2025 in the Quantum Computing Software and Algorithms category at the trade fair of the same name in Stuttgart. Strong partners and funding from the Federal Republic of Germany The industrial relevance of the technology is reflected in the company’s partnerships. In the QuCUN (Quantum Computing User Network) collaborative project, Aqarios is working together with partners SAP, BASF and LMU Munich to build an open, sustainable quantum computing ecosystem for Germany. The project, funded by the Federal Ministry of Research, Technology and Space (BMFTR), has a total funding volume of EUR 14.2 million. Beyond this, Aqarios GmbH is active in a large number of further initiatives, connecting cutting-edge research with real applications – from publicly funded research consortia to concrete projects together with industrial companies. In parallel, Aqarios is integrating the Luna platform into concrete applications for various industries. Together with the fintech company Divizend GmbH, the company is developing a product for the financial sector centered on portfolio optimization, which will come to market shortly – a direct vertical application of the Luna platform for institutional and private investors. Management Board and Supervisory Board The Management Board of Aqarios Quantum Technologies AG consists of Michael Lachner. The computer scientist and quantum computing expert, trained at LMU and TUM, is a co-founder of Aqarios and continues to serve as its managing director. The Supervisory Board consists of the finance and private equity expert Dr. Sebastian Kern (Chairman) and the two quantum computing specialists Dr. Sebastian Feld (Deputy Chairman) and Dr. Thomas Gabor. Dr. Sebastian Feld is a professor at Delft University of Technology in the Netherlands. He specializes in the architecture of quantum computers and their applications. Thomas Gabor is a Research Fellow at the University of Exeter in England. His research advances the development of software that links scientific algorithms such as quantum computing with artificial intelligence. Germany as a location: a strong environment for quantum computing With this stock market listing, Aqarios sends a signal for Germany as a location for quantum computing. Germany has one of the densest research and funding landscapes for quantum technologies in the world, supported by top universities, non-university research institutions and an industrially strong user base. As a spin-off from LMU Munich, an internationally leading center of quantum research, Aqarios exemplifies how market-ready quantum software emerges from German fundamental research. “Quantum computing will help determine industrial competitiveness in the coming years – and we want this value creation to take place in Germany and Europe,” says Michael Lachner, Management Board member of Aqarios Quantum Technologies AG and managing director of Aqarios GmbH. “As the first publicly listed quantum software company in Germany, we make this future technology accessible to investors just as much as to our industrial customers. With Luna, we have proven that quantum computing is already relevant for companies today – hardware-agnostic, application-oriented and scalable.” About Aqarios Aqarios GmbH is a spin-off from LMU Munich founded in 2021 and a leading provider of application-oriented quantum software. The company develops solutions for optimizing complex problems and, with its Luna platform, makes quantum computing practically usable for companies in the energy, finance, logistics, aviation and manufacturing sectors – hardware-agnostic, combinable across classical and quantum-based computing, and without requiring quantum expertise on the customer side. Since 2026, Aqarios has been represented on the capital markets through the publicly listed Aqarios Quantum Technologies AG (Düsseldorf Stock Exchange), which emerged from a SPAC transaction with Fonterelli SPAC 4 AG. Further information, including a detailed company presentation, is available in the Investor Relations section at www.aqarios.de.
