Finland’s position as a leader in commercial quantum technology receives a major boost from an investment in SemiQon by PostScriptum, the founder’s office led by Peter Sarlin. SemiQon is a world-leading supplier of cryo-optimized electronics for quantum computers.

SemiQon has reached a stage where its technology is productized with components now deployed in working quantum systems. SemiQon's customers include quantum computer manufacturers and system integrators.

The silicon chip developed by SemiQon is optimized for operation near absolute zero and is a key component in scaling quantum computers from today’s hundreds of qubits to hundreds of thousands, or even millions, of qubits. This is the level at which quantum computers are expected to surpass classical computers and supercomputers.

PostScriptum will provide SemiQon with a strong partner for scaling its commercial operations and accelerating growth.

“Quantum computing will define the next era of compute, and the million-qubit era will be powered by developments in control electronics, cooling and other enabling technologies. SemiQon provides cryogenic-ready quantum hardware that enables scalable, affordable, and sustainable quantum computing. Backing SemiQon is one of the most significant bets PostScriptum has made, and we are committed to it for the long term”, says Peter Sarlin, founder and Chairman of PostScriptum.

“Finland has become a leading hub for quantum technology research and commercialization in Europe and globally. When we first spoke with Peter, we immediately saw an opportunity to build a new success story around SemiQon’s technology”, says Antti Vasara, Chair of the Board of SemiQon.

Ready for industrial scale

SemiQon was established in 2023 to continue the commercialization of technology developed by VTT Technical Research Centre of Finland Ltd. After a three-year research phase, SemiQon entered the commercial phase earlier this spring.

The silicon-based Cryo-CMOS technology developed by SemiQon is a key platform for moving quantum computers from experimental laboratory systems to commercial products.

“This past spring has shown that there is significant interest in our product. Our customers’ trust is based on our ability to deliver top-quality components, and we are not tied to a single approach to building quantum computers. Our support for multiple quantum computing modalities is a significant advantage as we build critical enabling technologies for the future and strengthen Europe’s position in the global quantum industry,” says Himadri Majumdar, Co-Founder and CEO of SemiQon.

The cryo-optimized CMOS platform is designed and manufactured in line with existing standards for silicon-based semiconductors. It can be produced at industrial scale using the same methods and equipment as today’s silicon microchips. The company designs and manufactures its products in Otaniemi, Espoo.

“Our goal is to make SemiQon the world's leading enabling technology provider in quantum. What Peter and the team bring, expertise, networks, vision, is exactly the capital that matters most at this stage.” Majumdar continues.

What is Cryo-CMOS?

• It addresses a major bottleneck in scaling quantum computers by bringing the quantum processors readout and control electronics closer to the processor itself. The electronics must operate at temperatures close to absolute zero without interfering with the qubits.
• By enabling control and readout inside the cryostat, the technology can significantly reduce the wiring infrastructure currently required between the quantum processor and room-temperature electronics. This is a prerequisite for scaling quantum computers into commercially viable systems.
• Cryo-CMOS is compatible with existing semiconductor design and manufacturing standards and can be produced using established silicon chip manufacturing methods.
• Beyond quantum computing, the applications of SemiQon's Cryo-CMOS technology extend to other critical industries such as space technologies and high-performance computing.
