Insider Brief
- Swedish quantum startup Arkeon raised €594,200 (SEK 6.5 million) in seed funding to advance a technology designed to improve the precision and yield of superconducting quantum chip manufacturing.
- Arkeon’s approach enables qubit frequencies to be adjusted after fabrication by modifying Josephson junction resistance, helping compensate for production variations that can affect chip performance.
- The company plans to use the funding for technology development, customer validation and international expansion, and reports having letters of intent from potential customers and a pipeline of roughly 30 companies.
Swedish startup Arkeon has raised €594,200 (SEK 6.5 million) in seed funding to advance a manufacturing technology designed to improve the consistency and performance of superconducting quantum chips, according to information reported by EU Startups.
The investment was led by Chalmers Ventures, with participation from Navigare Ventures and Almi Invest. The company said the funding will support further development of its technology, customer validation efforts and preparations for expansion into international markets.
“We are seeing strong interest in this type of solution.” said Peter Hörstedt, CEO and co-founder of Arkeon, as reported in EU Startups. “As quantum chips grow, so does the need to adjust and optimise them without having to redesign the entire manufacturing process. With this funding, we can advance our technology and deepen our engagement with customers.”
Founded in 2025 by Peter Hörstedt, Andreas Nylander and Marcus Rommel, Arkeon is focused on addressing the difficulty of producing large numbers of nearly identical quantum bits, or qubits, considered one of the persistent engineering challenges facing superconducting quantum computing.
Superconducting qubits, which are used by several of the world’s leading quantum computing companies, rely on extremely precise manufacturing processes. Even small variations introduced during fabrication can alter the operating frequencies of individual qubits, reducing the performance of a quantum processor and lowering manufacturing yields.
Arkeon aims to address that problem by enabling adjustments to be made after a chip has already been fabricated. Rather than discarding chips that fall outside desired specifications, the company’s approach seeks to fine-tune them to improve uniformity and functionality.
According to EU Startups, Arkeon’s method allows individual qubits to be calibrated after production through a process that alters the resistance of Josephson junctions — microscopic structures that form the basis of many superconducting qubits. By applying controlled current pulse trains through the junction barrier, the company says it can tighten the placement of qubit frequencies and improve yield at the wafer level.
The ability to make post-production corrections could have important implications for the economics of quantum hardware manufacturing. As quantum processors scale from tens or hundreds of qubits toward much larger systems, improving production efficiency becomes increasingly important.
Low manufacturing yields have long been viewed as a barrier to commercial-scale quantum computing. Chips that fail to meet exacting standards can increase costs and slow development timelines. Technologies that improve reproducibility could help hardware developers accelerate the transition from laboratory prototypes to more reliable commercial systems.
Arkeon is initially targeting organizations developing superconducting quantum processors, including both industrial firms and research institutions working to expand the scale and capabilities of quantum computers.
The company told EU Startups that it has already secured letters of intent from several prospective customers and has identified approximately 30 companies within its commercial pipeline.
The new funding will be used to continue refining the technology and validating it with potential users, while positioning the company for broader international growth, the company told EU Startups.
