A beacon of quantum research: Paderborn University opens state-of-the-art PhoQS Lab

After three years of construction, the University of Paderborn officially opened the Photonic Quantum Systems Laboratory (PhoQS Lab) on February 26. The university welcomed numerous representatives from politics, science, and industry to the opening ceremony, including North Rhine-Westphalia's Minister-President Hendrik Wüst, State Secretary Dr. Rolf-Dieter Jungk, and Science Minister Ina Brandes. The new research building will house the Institute for Photonic Quantum Systems (PhoQS), where researchers from various disciplines will collaborate on the further development of photonic quantum technologies. The goal is to translate excellent fundamental research into concrete applications and to develop pioneering key technologies for the future.

The research focuses on light-based, or photonic, applications, which are considered particularly promising for secure communication, high-performance data transmission, and high-precision sensing. Participants emphasized the enormous potential of quantum technologies for business and society – from tap-proof quantum cryptography to innovative medical diagnostic procedures. The development of a strong research ecosystem will foster new national and international collaborations with leading institutions and companies. This is intended to sustainably strengthen the competitiveness of North Rhine-Westphalia as a research location.

The PhoQS Lab also sets standards in terms of infrastructure: The new building offers state-of-the-art research conditions across approximately 7,950 square meters. A physical separation between office and laboratory areas ensures vibration-free measurements. Particularly sensitive equipment is installed on specially decoupled foundations to minimize vibrations. A cleanroom of approximately 1,000 square meters enables experiments to be conducted under strictly controlled conditions – crucial for precise work in the field of quantum photonics.

A key research focus is a miniature photonic quantum chip, which could potentially form the basis for a quantum internet with networked quantum computers. Those responsible for the PhoQS Lab see it as a milestone for international quantum research and an important contribution to Germany's technological sovereignty.

Even in the planning phase, the project received the highest rating of "outstanding" from the German Council of Science and Humanities. Funding of approximately €82.7 million was provided jointly by the state of North Rhine-Westphalia and the federal government, supplemented by the university's own funds.
