QuTech

Overview

QuTech is a world-class quantum research and development institute established in 2014 as a joint venture between Delft University of Technology (TU Delft) and the Netherlands Organisation for Applied Scientific Research (TNO). Headquartered in Delft, Netherlands, it operates as a mission-driven public research institution rather than a commercial entity, functioning as one of Europe's foremost centers for quantum technology. QuTech's mandate spans fundamental research, applied development, and ecosystem building—bridging academic discovery and industrial application in quantum computing and quantum internet technologies. It receives substantial structural funding from the Dutch government and the European Union, supplementing project-based grants and industry partnerships.

QuTech pursues two primary qubit modalities simultaneously: superconducting qubits and silicon spin qubits. The silicon spin qubit program is among the most advanced globally, exploiting the same semiconductor fabrication infrastructure that underpins classical computing—a strategic alignment that could enable eventual integration with CMOS manufacturing. The superconducting program, while competing in a more crowded field, has produced significant fidelity advances and feeds into the institute's cloud platform. Separately, QuTech leads a significant research collaboration with Microsoft on topological qubits based on Majorana fermion physics, a high-risk, high-reward bet that Microsoft's Azure Quantum team has identified as its long-term path to fault-tolerant qubits. This relationship gives QuTech unique visibility into one of the most closely watched moonshot programs in quantum computing.

On the quantum internet front, QuTech leads the OpenSuperQ and Quantum Internet Alliance efforts and is executing on a multi-year roadmap to establish a metropolitan quantum network across Dutch cities. The institute spun out Quantum Inspire, a cloud-based quantum computing access platform that offers users the ability to run algorithms on both superconducting and spin qubit hardware. Quantum Inspire is notable as one of the few platforms worldwide offering real spin qubit access. QuTech also plays a central role in the Dutch National Agenda Quantum Technology and European Quantum Flagship, positioning it as a policy anchor as well as a technical one.

Because QuTech is a non-commercial research institute, it does not have equity investors, a stock listing, or conventional revenue streams—making it an indirect rather than direct investment target. However, its centrality to the European quantum ecosystem means it is a critical partner, talent source, and technology licensor for commercial entities investors may be evaluating. Companies and funds with exposure to European quantum infrastructure, Netherlands-based deeptech, or Microsoft's quantum ambitions should track QuTech as a leading indicator of where the technology frontier is moving.

Leadership

Technology

QuTech's technical portfolio is unusually broad for a single institution. Its silicon spin qubit program exploits electron or hole spins confined in silicon quantum dots, fabricated using techniques compatible with standard CMOS processes. This gives the program a credible long-term scaling argument: if silicon spin qubits can be made with sufficient fidelity and yield, industrial semiconductor fabs could eventually produce them at scale. QuTech researchers have demonstrated single-qubit gate fidelities exceeding 99.9% and two-qubit gate fidelities above 99.5% in silicon, among the best reported globally for this modality as of early 2026. Coherence times in isotopically purified silicon-28 exceed milliseconds for electron spins, providing a favorable operating environment. The primary challenge—which QuTech is actively working on—is scaling beyond a handful of qubits while maintaining these fidelities, and developing the classical control electronics to manage large arrays.
