SemiQon provides silicon quantum‑dot qubits fabricated with standard 28 nm CMOS processes, combined with cryogenic‑CMOS transistors that operate below 4 K. The integrated platform places control logic (DACs, multiplexers, amplifiers) on the same chip, reducing interconnect complexity and power dissipation for scalable quantum processors. It is offered as ready‑to‑use quantum‑dot devices and cryo‑optimized ICs compatible with existing dilution‑refrigerator setups.

Problem
Current quantum computing platforms rely on heterogeneous, non‑CMOS qubit implementations that are expensive, difficult to scale, and require custom cryogenic control electronics, limiting progress toward the million‑qubit threshold. Researchers and system integrators also lack cryogenic‑optimized transistors that can operate reliably at the temperatures required for quantum processors.
Solution
SemiQon delivers silicon‑based quantum processors built from quantum‑dot qubits that are compatible with standard CMOS manufacturing, enabling high‑volume, cost‑effective production. The company’s Cryo‑CMOS technology provides transistors and control circuits that function reliably at cryogenic temperatures, eliminating the need for separate, room‑temperature control hardware. By integrating qubit arrays with cryogenic‑ready control logic on a single silicon substrate, SemiQon’s platform reduces interconnect complexity and power dissipation, paving the way for dense, scalable quantum chips. The solution is offered as ready‑to‑use silicon quantum dot devices and a suite of cryogenic‑optimized ICs that can be incorporated into existing dilution‑refrigerator setups, accelerating research and shortening time‑to‑market for quantum hardware developers.
Target Audience
Primary customers are quantum‑hardware research labs, OEMs developing scalable quantum computers, and organizations in aerospace or defense that require cryogenic‑ready semiconductor components for space‑qualified quantum systems.
