The feature appears in the 6 March 2026 issue of Talouselämä and includes an interview with our CEO Himadri Majumdar and CTO Janne Lehtinen. In the article they discuss the current state of the quantum computing industry, the key scaling challenges facing the field, and SemiQon’s approach to solving them.

Tackling one of quantum computing’s biggest bottlenecks

Scaling quantum computers from today’s laboratory systems to large-scale machines capable of solving real-world problems remains one of the biggest challenges in the field. One key limitation lies in how quantum processors are controlled. The electronics responsible for operating qubits typically sit outside the cryogenic environment where the processor itself must run.

Today’s quantum computers require multiple control cables for every qubit. Scaling that architecture to thousands or even millions of qubits quickly becomes impractical.

“Three million cables doesn’t sound very good,” Lehtinen notes in the interview.

At SemiQon, our work focuses on cryo-optimized CMOS electronics. These are control electronics designed to operate in extremely low-temperature environments. Today, the primary users of this technology are within quantum computing, but it can also benefit other demanding cryogenic environments beyond quantum computing, including space applications.

Our approach moves control electronics closer to the qubits by allowing them to operate directly inside the cryostat. This reduces the amount of wiring required, lowers cooling loads and simplifies the overall system architecture.

By integrating control electronics close to the qubits at cryogenic temperatures, quantum hardware becomes more scalable, more energy efficient and ultimately easier to build.

“At the moment, each qubit requires roughly two to three control cables. The idea is that when a single wire comes down, our technology can distribute it to several devices. This allows us to build the quantum computer using far fewer connections,” Lehtinen explains in the interview.

SemiQon’s CEO Himadri Majumdar says the company currently holds a significant technological lead in this area. “We are three years ahead of competitors.”

Entering the next growth phase

SemiQon is now entering its next growth phase with commercially available cryogenic CMOS electronics. At the beginning of February, we celebrated our three-year journey. It was a moment to reflect on how a four-founder team has grown into a startup of more than 30 people preparing for its next stage of growth.

Our team of curious minds, together with the strong support of our partners, investors and the wider quantum ecosystem, has played a key role in our journey so far and will continue to shape the road ahead.
