About semiqon

We deliver cryogenic CMOS chips for next-generation critical technologies and build silicon-based quantum processors for the million-qubit era.

In Quantum

At SemiQon, we build quantum processors for the million-qubit era. We want to develop the technology needed to close the gap between today’s reality and future possibilities of quantum computing.

Our semiconductor-based solutions respond to three major challenges that are currently slowing down the development of quantum computers globally – their scalability, price, and sustainability. Our technology allows us to fabricate quantum processors in a way that supports scaling up manufacturing efficiently while also lowering costs. The chips and control electronics we manufacture also enable the quantum computer to operate at warmer temperatures – thus requiring only a fraction of the energy needed for alternative solutions.

As we develop our solution, instead of starting from scratch, we build the next revolution of computing power on decades of technological development and know-how of semiconductors that have made our current digital era possible. We benefit from an existing industry, which will support the scale-up and commercialization of our technology and boost European competitiveness and technological sovereignty in quantum.

We see that specialization is speeding up in the quantum field and believe that the entire industry will benefit from more companies doing fewer things. That is why SemiQon’s strategy is to focus our efforts on where we can bring the most value and collaborate with partners who excel at other things.

And Beyond

The problems that need to be solved to realize the potential of quantum can bring immediate value also in other critical technologies. Beyond quantum, innovations like SemiQon’s power-efficient electronics developed for extreme temperatures also have major advantages for areas such as space tech and high-performance computing.

SemiQon’s cryogenically optimized CMOS transistors, or cryo-CMOS for short, enable a paradigm shift in energy consumption and dissipation, and could be used to address one of the most pressing challenges in HPC.

A spin-out from VTT

The founding team of SemiQon came together at VTT (Technical Research Centre of Finland), where we worked in different capacities with microelectronics, quantum, and innovation management.

As researchers in the quantum field, we are constantly exposed to the many expectations directed at quantum computers – from developing life-saving drugs to achieving climate neutrality. Ambitions are high, and for good reason.

We believe in the potential of quantum but also understand that overcoming the challenges of scaling up quantum computers from a handful of qubits – or even a few hundred – to hundreds of thousands and then millions, requires innovation, commitment, and technical breakthroughs. We felt confident that our solutions could offer a viable and cost-effective solution, so, we decided to get to work on those breakthroughs to help realize the promise of quantum.

In 2022, SemiQon got its start as part of VTT’s Launchpad incubator. During the year, we worked on developing the business plan and surrounding ourselves with a group of experienced investors and mentors. In early 2023, it was finally time to kick off independent operations.

We are based at the Micronova Center for Applied Micro and Nanotechnology in Espoo, Finland, and have access to a facility that allows us to carry out fast design and fabrication cycles.

By 2025, we have consistently checked off business and technology milestones. We have built an extensive global network of partners, filed several patents, secured significant public funding, and launched two of our first commercially available products.

We are proud to say that we are on track to realize the potential of quantum computing. Our way.

Secured EUR 2 million in funding by February 2023. Lead investor Helsinki-based deep tech investor Voima Ventures.

By February 2023, we had secured EUR 2 million. We are proud to be backed by a number of committed investors, including Lunar Ventures, Dhyan Ventures, Tiny Supercomputer VC, Atomico Angel programme, and some strategic angel investors. We are lucky and proud to work with investors that are committed to driving innovation and bring valuable experience from within and outside the quantum industry.

Since our initial funding round, we have been successful in several highly competitive funding applications independently and through different consortium projects. In the spring of 2025, we had the pleasure to announce that the European Innovation Council EUR 2.5 million in a competitive, non-dilutive grant and an additional EUR 15 million of equity-based ear-marked funding.
