Arkeon Technologies AB

Arkeon Technologies is addressing one of the biggest bottlenecks in building scalable superconducting quantum computers: the lack of precise and efficient post-fabrication tuning of qubit frequencies.

In today’s quantum processors, small variations in fabrication lead to frequency collisions and crosstalk between qubits, limiting performance and scalability.

Arkeon’s patent pending post-fabrication trimming process allows precise adjustment of Josephson junction resistances directly on completed chips, enabling controlled tuning of qubit frequencies without multiple cooldowns or redesign cycles. This approach integrates seamlessly with existing foundry processes and eliminates the need for costly fabrication iterations.

By solving the frequency collision problem, Arkeon unlocks higher qubit yields, improved device uniformity, and faster development cycles, critical enablers for quantum computing at scale. The potential impact spans across leading quantum hardware developers seeking to accelerate time-to-market, reduce costs, and push the boundaries of processor performance.
