Arkeon Raises $650K Seed to Boost Quantum Chip Precision

Jan de Vries · 2026-06-12

Arkeon Technologies, a DeepTech startup based in Gothenburg, Sweden, just closed a $650,000 Seed round (roughly SEK 6.5 million) to push its technology forward. The company is focused on making large-scale superconducting quantum computing a reality, and this funding is aimed at improving how quantum chips are made -- specifically, boosting precision and quality in production. ### The Funding Details The round was backed by Chalmers Ventures, along with Navigare Ventures and Almi Invest. These investors are betting on Arkeon's unique approach to a problem that's been holding the quantum industry back. "We're seeing strong interest in this type of solution," said Peter Horstedt, CEO and co-founder of Arkeon. "As quantum chips grow, the need to adjust and optimize them without redesigning the entire manufacturing process becomes critical. With this funding, we can advance our technology and deepen our engagement with customers." ### What Arkeon Actually Does Founded in 2025 by Peter Horstedt, Andreas Nylander, and Marcus Rommel, Arkeon has developed a method for superconducting quantum chips where qubit frequencies are tweaked after fabrication. The goal? To improve precision, quality, and yield. Here's the problem: small production variations can make chips underperform. That affects accuracy and yield. But Arkeon's approach lets them fine-tune each chip after it's made. Think of it like adjusting a musical instrument after it's been built -- you can get it perfectly in tune, rather than hoping it sounds good straight out of the factory. The company uses controlled current pulse-trains through the junction barrier to adjust junction resistance, tighten frequency placement, and improve wafer-level yield. It's a clever way to solve a messy problem. ### Why This Matters for Quantum Computing Quantum computing is still in its early days, but it's moving fast. The industry is at a point where scaling up systems is the next big hurdle. Arkeon is targeting the market for superconducting quantum processors, where both big industrial players and top research labs are working together to build more complex systems. The startup says it already has letters of intent from several potential customers and a pipeline of about 30 companies. That's a strong signal that there's real demand for what they're building. ### The Bigger Picture "Arkeon is addressing a clear challenge that the quantum industry faces in its next phase," said David Storek, Investment Director at Chalmers Ventures. "What stands out is the combination of smart and advanced innovation, a defined use case, and early market interest. This is a solution with the potential to play an important role as quantum systems move toward industrial deployment." With this capital, Arkeon plans to fund continued development, customer validation, and prep for an international market. They also want to strengthen their portfolio in next-generation computing and help companies tackle fundamental technical challenges in emerging industries. ### What's Next? For a startup that's barely a year old, Arkeon is moving fast. The seed round gives them runway to prove their technology works at scale. If they can deliver on the promise of better quantum chips with higher yields and lower costs, they could become a key player in the quantum supply chain. It's a space worth watching. As quantum computing inches closer to real-world applications, the companies that solve the manufacturing and precision problems will be the ones that matter most.
