Arkeon Technologies, a Gothenburg-based quantum computing startup, raised €594.2k in seed funding to advance a technology that improves the performance and yield of superconducting quantum chips after fabrication. Founded in 2025, the company has developed a method that adjusts qubit frequencies post-production, helping compensate for manufacturing variations that can affect chip accuracy and stability.
The approach works by applying controlled current pulse trains to modify junction resistance, enabling more precise frequency placement without requiring manufacturers to redesign existing fabrication processes. By allowing each chip to be individually optimized after production, the technology aims to improve reproducibility, increase wafer-level yields and reduce manufacturing costs as quantum processors become more complex. The funding round, backed by Chalmers Ventures, Navigare Ventures and Almi Invest, will support technology development, customer validation and international expansion.
For quantum hardware developers, the solution addresses a key manufacturing bottleneck as the industry works toward larger-scale commercial quantum systems.

What's Driving This Trend
- Post-fabrication Quantum Tuning
- Adjustable qubit frequencies after chip production create new pathways for higher-yield quantum processors without costly fabrication redesigns.
- Wafer-level Yield Optimization
- Manufacturing variability in quantum chips is becoming a software-adjacent hardware opportunity as precision alignment improves reproducibility across wafers.
- Scalable Superconducting Systems
- Commercial quantum expansion depends on chip-level correction methods that support larger processor architectures with improved stability and lower production costs.
Who This Affects Most
- Quantum Computing
- Hardware developers gain a route to more reliable superconducting processors as post-production calibration reduces barriers to scalable commercial systems.
- Semiconductor Manufacturing
- Advanced fabrication ecosystems can benefit from alignment technologies that preserve existing processes while improving output quality for emerging quantum components.
- Deep Tech Investment
- Early-stage capital is increasingly focused on specialized quantum infrastructure that addresses manufacturability, validation and global commercialization challenges.
