We are proud to present our Annual Report for 2025. UNESCO declared 2025 the International Year of Quantum Science and Technology, marking the 100th anniversary of the birth of quantum mechanics as a formal scientific discipline. For QuTech, this was an ideal opportunity to highlight our mission: scaling reliable quantum computers and networks, from fundamental qubits to systems, software, and applications, and in close collaboration with a thriving quantum technology ecosystem for which we act as an incubator and enabler.

In Delft, QuTech and QDNL Delft organised the Delft Quantum Showcase, where researchers, startups and industry partners from the Delft hub presented their work and forged new collaborations, and in the second half of the year, QuTech chaired the international conference Superconducting Qubits & Algorithms (together with partners), as well as the biennial Quantum Networking Workshop.

Scientifically, QuTech achieved major milestones in 2025 with direct implications for scalability and practical application. One highlight was the development of QNodeOS, a control system for quantum networks that enables programmable, hardware-independent network applications. In quantum computing, we demonstrated that an electron can be moved across micrometer scales while preserving its spin, offering new design flexibility for on-chip connectivity. Another example was the controlled creation and movement of Majorana bound states in a chain of quantum dots by QuTech researchers; a significant step toward topological qubits.

Commercialisation remained a core focus. The startup ecosystem originating from QuTech, TU Delft, and TNO saw growing investments in 2025 and the joint Delft-grown companies now employ over 500 people. The total number of professionals in research and industry within the Delft quantum hub has grown to more than 1,000 people. Additionally, QuTech spun off another new startup – Frostbyte – (after spinning off three new companies in 2024), we saw more quantum companies moving to Delft to set up a presence, and our computing demonstrator Quantum Inspire 2.0 – built in collaboration with the ecosystem – received further upgrades allowing it to play a role in future use case research.

At QuTech we are all working hard to further develop our role as a cornerstone insitute for the development of quantum technology in Europe and the Netherlands. We are proud to do our part building a vision for the future and developing policy and as our field moves closer to real-world applications.
