SemiQon, based in Espoo, Finland, has successfully produced, tested, and shipped to strategic partners a 4-qubit silicon-based quantum chip. These chips are now being shipped globally to support research and development efforts aimed at accelerating the utilization of quantum computing. The company’s approach combines classical and quantum elements at cryogenic temperatures, demonstrating low noise and enhanced transistor control, crucial for scalable quantum computers. As part of their technical strategy, SemiQon will be using fully-depleted silicon-on-insulator metal-on-semiconductor (FDSOI-MOS) transistors that will operate at cryogenic temperatures for the classical functionality allowing close integration with the silicon-based spin qubits.
The chips were built at the the Micronova Center for Applied Micro and Nanotechnology in Espoo. Dr. Himadri Majumdar, CEO and Co-founder of SemiQon, emphasizes the importance of hardware contribution in achieving quantum supremacy sustainably and affordably. The company has written a technical paper about their developments which will be published in a technical journal soon.
