SemiQon builds silicon-based quantum processors for the million-qubit era. The Espoo-based startup powers the scale-up of quantum computing with silicon-based quantum processors. Believing in the marriage of quantum and semiconductors, the company's semiconductor-based technology delivers scalability through powerful, resilient, and cost-effective quantum processors.
Who is Himadri Majumdar?
I am the CEO and co-founder of SemiQon. I have been living in Finland for the last two decades with a career spanning research, innovation and innovation management. A significant part of my professional career has been at VTT in diverse research and management roles.
Espoo has been home to me and my family for over 12 years now, and it has been memorable from both a social and professional perspective. I look forward to living and working in Espoo for years to come.
What's SemiQon's story and what has helped you to get where you are now?
I, along with my co-founders Mika Prunnila, Janne Lehtinen, and Markku Kainlauri, spun out of VTT with SemiQon in early 2023. It has been a strong mixture of hard work and fun to build the company. The support from the local quantum and business ecosystem has been pivotal for our success. I believe there is an enormous amount of expertise and talent in the Otaniemi region that, if successfully tapped into, can generate significant value. I am passionate about technology and will do my part to ensure SemiQon takes that expertise to the world.

A leading quantum and semiconductor community in Europe
Espoo's innovation community in Finland offers globally leading quantum technology and semiconductor expertise, talents, and infrastructure — and will be one of Europe's significant quantum and semiconductor industry hubs.

What problems do your quantum processors solve?
At SemiQon, we build silicon-based quantum processors for the million-qubit era. Our mission at SemiQon is to power the scale-up of quantum computing with silicon-based quantum processors. Our semiconductor-based technology is focused on delivering scalability through powerful, resilient, and cost-effective quantum processors.
Our solution responds 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 the efficient scale-up of manufacturing while doing it at a lower cost and warmer temperatures – requiring significantly less energy than alternative solutions that are based on non-standard materials.
SemiQon's technology builds upon decades of development and know-how from the semiconductor industry, making our silicon processors commercially competitive and well-suited for mass manufacturing. We believe that the marriage of quantum and semiconductors not only scales up quantum computing effectively but also boosts manufacturing, builds resilience, and supports technological sovereignty. Investments made in infrastructure will give Europe and the US a strong advantage in the future of the computational hardware industry.

What makes SemiQon's quantum processors unique?
By leveraging semiconductor quantum-dot qubits and cryogenic ultra-low dissipation CMOS hardware, our scalable quantum processing units (QPUs) tackle the challenges of scalability, sustainability, and affordability in quantum computing. Our technology expands upon the initial demonstration of monolithically integrated on-chip quasi-dissipationless cryogenic multiplexers, paving the way for scalable quantum computing solutions.
SemiQon intends to disrupt the global quantum computing market by creating state-of-the-art silicon spin-qubit quantum processing units at a quality, cost, and speed that is beyond the current market's availability. SemiQon's unique design and fabrication methodologies and facilities allow us to have a very fast turn-around time for customised quantum processing units that can be coupled with full-stack design and architecture, as required by the customer, including academic research groups.
Our operational model is unique and is different from that of other competitors globally. We focus our resources and efforts on building the best possible quantum processing units and intend to collaborate with partners who are best in other aspects.
How do SemiQon's quantum processors advance sustainability goals?
SemiQon's ambition is to build scalable, affordable, and sustainable quantum processors for quantum computers. So, sustainability is a key developmental goal for us. We are not only considering environmental sustainability with our approach of relatively high-temperature quantum processors, low-temperature processes, like ALD, and choice of sustainable and abundant raw materials like silicon, but we are also looking at aspects of a sustainable supply chain and sourcing for manufacturing. Doing local manufacturing is one such important aspect.
Who are your customers?
Our customers include research groups, with whom we collaborate closely to bring scalable quantum computing solutions closer to reality, and system integrators who intend to build full-stack quantum computers using the best available components, including quantum processor units. We are also open to strategic partnership with companies, agencies and end-user companies who intend to build customised quantum computers for specific needs and applications.
