PostScriptum Invests in Quantum Hardware Developer SemiQon

Insider BriefPRESS RELEASE — With the investment, PostScriptum will become a shareholder in SemiQon, a Finnish quantum hardware company building one of Europe’s most ambitious platforms for next-generation quantum technology. The investment will help accelerate the commercialization of SemiQon’s breakthrough technology and support the company’s path toward becoming a leading European quantum hardware company.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 scaleSemiQon 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?TopicsShare Get the latest research, company news, and market intelligence every week. MENTIONED IN THE ARTICLESemiQon aims to power the scale-up of quantum computing by building quantum processors.VTT is a Finnish, fully state-owned limited liability company that helps customers create new business and solve global challenges with science and technology. They help organizations that develop quantum technologies in scaling up, integrating, and interfacing devices towards profitable business cases. They have expertise in superconducting, photonic, and semiconducting technology platforms and want to be a leading foundry for producing quantum chips and providing services that make quantum computing possible in practice. Quantum services they provide include fabrication, process development, device modelling and design, device and systems characterization, quantum metrology, quantum control solutions including 3D integration, and thermal engineering.More in Research 2026 © Resonance Alliance Inc.
