Germany: A Quantum Champion? How Aqarios Quantum Technologies Is Winning Over BASF, E.ON and IBM – Innovations at Quantum eMotion and Amazon

Quantum eMotion Focuses on IT Security

In terms of public perception, the topic of quantum computing is somewhat further along in North America. Here, Quantum eMotion has already made a name for itself. While computing power is growing exponentially worldwide, the threat to IT security is growing in tandem. Cybercriminals and intelligence agencies have long been systematically intercepting and caching encrypted data streams to crack them later using quantum computers. The Canadian company Quantum eMotion, listed on the TSX Venture and the NYSE American, is taking on this trend. In fiscal year 2025, Quantum eMotion generated virtually no measurable revenue and posted a net loss of CAD 10.5 million. Technologically, the Canadian company does not rely on photonic approaches, but rather on a patented quantum random number generator based on the unpredictable movement of tunnelling electrons. Together with TSMC, the world's largest chip manufacturer, Quantum eMotion has successfully tested a tiny security chip in simulations that generates 1.8 billion completely unpredictable random signals per second from the quantum world. According to a market analysis by ICV, the global market for such chips could grow from USD 150 million in 2024 to USD 2 billion by 2033. However, as long as Quantum eMotion does not generate significant revenue, this growth outlook remains hypothetical.

Amazon and Quantum Error Correction

The US cloud giants are pulling out all the stops to push hardware to its physical limits. While Amazon offers access to various quantum systems through its cloud division's Braket service, it is also conducting research on its own chips at its in-house Centre for Quantum Computing. The core problem for Amazon and other industry players remains the fragility of qubits (quantum bits: units of data in quantum computing analogous to "bits") in the face of thermal and electromagnetic noise. Superconducting computers often require up to a thousand physical qubits to represent just a single stable, error-corrected qubit. This consumes enormous resources. With its prototype chip, Ocelot, Amazon introduced an innovative method based on Cat qubits that reduces the immense resource requirements for quantum mechanical error correction by up to 90%. In this architecture, microwave-frequency photons in special cavity resonators suppress disturbances through purely physical means. Amazon's Ocelot chip combines several of these methods to minimize the error rate as much as possible. However, to achieve mass-market viability, Amazon will likely need to inject additional capital.

Aqarios Quantum Technologies: German Quantum Pioneer Already Winning Over Global Corporations

While other companies are still debating architectures, the Munich-based quantum company Aqarios Quantum Technologies is already setting standards. The company was founded in 2021 as a direct university spin-off from the Munich QAR Lab at Ludwig Maximilian University. At the heart of Aqarios is the Luna software platform. This software serves as a universal translation layer between core business problems and complex quantum computers. As a result, Aqarios customers need neither to hire physicists nor to delve deeply into cryptic quantum circuits. Luna takes planning data, converts it into binary quadratic optimization models, and automatically forwards it to the most suitable backend—whether that is classical supercomputing, D-Wave quantum annealers, or gate-based processors. Real-world applications demonstrate just how powerful this concept is.

For a complex rail network with 47 tracks, 6 stations, and 6 trains, Aqarios reduced the computational load through mathematical decomposition so elegantly that a quantum annealer solved the problem error-free with fewer than 240 qubits. On a gate-based quantum processor, using a special algorithm (QAOA), even fewer than 40 qubits were sufficient to achieve a solution close to the optimum. Major corporations such as BMW, BASF, E.ON and SAP are already drawing on Aqarios' expertise for their most complex tasks. For the young company, these business relationships are a major accolade. Just a few days ago, a collaboration with IBM was added to the mix: effective immediately, new quantum optimization software from Aqarios, called the "Constrained Quantum Optimizer", is available in the IBM Qiskit Functions Catalog. IBM is thus providing its customers with quantum solutions.

Aqarios Benefits from Millions in Funding - A Strong Starting Point

The Munich-based company does not rely solely on short-term consulting contracts; rather, it is also driving the scaling of its portfolio through research. Together with partners such as SAP and BASF, Aqarios is a driving force in the QuCUN collaborative project. The Federal Ministry of Research, Technology and Space (BMFTR) is funding QuCUN with a total of EUR 14.2 million to accelerate the technology transfer of quantum software to small and medium-sized enterprises. The company's financial position also stands out positively compared with overseas competitors, some of whom operate with high risk. Aqarios is debt-free and rests on a solid equity foundation. In fiscal year 2025, Aqarios generated gross profit of EUR 1.06 million with a manageable net loss of just under EUR 459,000. Following its initial public offering (IPO) as part of a reverse takeover in July, Aqarios is listed on the Düsseldorf Stock Exchange's over-the-counter market as the first purely German quantum software stock. The share capital consists of 2.5 million no-par value shares, with T.A.R. Equity, as a stable anchor shareholder, holding approximately 60% of the shares. The remaining 40% is in free float. With a market capitalization of around EUR 35 million, Aqarios has largely flown under the radar of the markets so far.

A look at the international competition reveals some extreme valuations. US competitors such as Rigetti and D-Wave are at times traded at astronomical price-to-sales (P/S) ratios of 795 and 314, respectively, while the flagship company IonQ is valued at a P/S ratio of 82. Aqarios, by contrast, trades at around EUR 14.00 per share and is valued at a price-to-gross-profit multiple of approximately 32.6, based on 2025 gross profit of EUR 1.06 million, which includes both revenue and subsidies. While such comparisons are simplistic and, taken in isolation, do not carry decisive weight, there is much to be said for Aqarios. The growing momentum surrounding quantum technology, Aqarios' illustrious list of customers and collaboration partners, and the rising demand in an increasingly complex world are likely to bolster the equity story further. Aqarios has everything it takes to become one of the next "Made in Germany" success stories.
