$140M SPAC Funds Aqarios’ Public Quantum Computing Debut

Aqarios Quantum Technologies AG began trading on the Düsseldorf Stock Exchange this week, becoming, to their knowledge, the first pure-play quantum computing company publicly listed in Germany. The listing follows a transaction with Fonterelli SPAC 4 AG, accelerating the company’s growth since its founding in 2021 as a spin-off from LMU Munich. Aqarios intends to use the funds to expand its quantum application platform, Luna, which allows businesses to access quantum computing without specialized in-house expertise. “Quantum computing will help determine industrial competitiveness in the years ahead—and we want that value creation to happen in Germany and Europe,” says Michael Lachner, CEO of Aqarios Quantum Technologies AG, signaling a commitment to bolstering European innovation in the field.

The company’s shares now trade on Börse Düsseldorf, a significant step for European investors seeking exposure to this specialized field. Aqarios’ core offering, the Luna quantum application platform, is designed to democratize access to quantum computing by simplifying hardware and algorithms. Luna’s hardware-agnostic approach, allowing access to multiple quantum systems, is a key differentiator, enabling businesses to focus on problem-solving rather than infrastructure. “With Luna, we’ve shown that quantum computing is relevant for businesses today—hardware-agnostic, application-driven, and scalable,” Lachner added. Aqarios’ commitment to practical application is further underscored by partnerships with industry leaders like BASF, E.ON, and MTU Aero Engines, as well as participation in the QuCUN initiative alongside SAP and LMU Munich, supported by the German Federal Ministry for Research, Technology and Space. The company’s supervisory board, chaired by Dr. Sebastian Kern and including Dr. Sebastian Feld of TU Delft and Dr. Thomas Gabor of the University of Exeter, provides a blend of financial and quantum expertise to guide future growth.

Luna Platform Enables Hardware-Agnostic Quantum Optimization

Organizations seeking to explore quantum solutions often face the challenge of aligning algorithms with specific, and often limited, quantum processing units. This requires significant in-house expertise and restricts the scalability of potential applications. Aqarios Quantum Technologies AG addresses this issue with Luna, a quantum application platform designed to decouple software development from underlying hardware. Launched as a spin-off from LMU Munich in 2021, the company has rapidly transitioned from academic research to a publicly traded entity, reflecting the accelerating pace of innovation in the field. A key differentiator for Luna is its hardware-agnostic approach, allowing customers to access diverse quantum systems through a single interface, eliminating vendor lock-in and enabling optimization based on the best available technology for a given problem.

By combining classical and quantum computing resources, Luna dynamically selects the most effective solution, ensuring practical results even with the limitations of current quantum hardware. This strategy garnered industry recognition with the Quantum Effects Award 2025 for Quantum Computing Software and Algorithms, validating the platform’s pragmatic design.

Aqarios Quantum Technologies AG’s recent public listing is connected with collaborative efforts like the QuCUN initiative, solidifying Germany’s position within the growing quantum computing landscape. Following a successful transaction with Fonterelli SPAC 4 AG, Aqarios has officially entered the public markets, providing resources to bolster its quantum application platform and expand its reach. The QuCUN framework aims to establish a robust and sustainable quantum computing ecosystem within Germany, fostering innovation and practical application, and the company’s Luna platform, designed to simplify quantum hardware, is central to this vision. Sebastian Kern, with Dr. Sebastian Feld of TU Delft as Vice Chairman, leads the supervisory board, and this blend of investment, collaboration, and accessible technology positions Aqarios, and by extension, the German quantum ecosystem, for continued expansion and impact.
