At QuTech, we believe in an ecosystem’s approach and work with companies and spin-outs in our direct surroundings. The companies in the Delft ecosystem are transforming laboratory discoveries into real-world applications, broadening the quantum realm to encompass a growing number of people and disciplines. They include startups and scale-ups in quantum computing and quantum networking, but also international companies who are joining House of Quantum to set up a Dutch or European presence close to the quantum talent that has gathered here.

Here are some of the companies that grew out of QuTech or TU Delft.

• Groove Quantum, a QuTech spinout launched in 2024, is tackling the qubit scalability challenge with its unique germanium-based quantum technology. Germanium qubits offer high quality, a compact footprint, and seamless integration with existing semiconductor manufacturing processes: all key advantages for accelerating scale-up.
• FrostByte spun out of QuTech in 2025 to develop cryogenic electronics that address the scaling bottlenecks facing quantum technologies. They use their deep expertise in cryogenic CMOS design to develop solutions that enable customers to work with the next generation of quantum devices.
• After operating as an engineering group inside QuTech for three years, Q*Bird launched in 2023. They provide technology for quantum secure networking, upgradable to future connectivity. One example is a new quantum network they are building for the Port of Rotterdam stakeholders to use for their critical communication systems.
• QuTech spinoff QuantWare, which finds its origins in the DiCarlo lab, is the leading supplier of quantum processors, with technology that will allow them to significantly scale the number of qubits in a single processor.
• Spin-out company Orange Quantum Systems, launched in 2020, designs and delivers equipment for testing, characterising, and benchmarking quantum chips ranging from a few qubits to several hundred.
• QuTech spinoff QBlox deliver qubit control electronics. They are one of the fastest growers in the quantum landscape: in 2023, Deloitte named Qblox the fastest-growing high-tech hardware company in the Netherlands. In 2024 they won the Deloitte Fast 50 Deep Tech Award for innovative companies that are driving advancements in deep tech.
• Other examples of pioneering quantum companies that originated in Delft and are part of its ecosystem are Delft Circuits, QphoX and Single Quantum.
