CITC participates in QuLight Detection project
June 25, 2025 – CITC participates in the QuLight Detection project. The aim of this project is to develop a single photon detector (SPD) that is significantly more scalable than existing detectors. This SPD will be used in quantum computers, which allows for significant upscaling.
No cryostats required
Our SPD is based on a highly efficient single photon avalanche detector (SPAD). Unlike SNSPDs, SPADs do not require cryostats for operation, which leads to:
- a tenfold decrease in energy consumption
- a thirtyfold reduction in size, and
- a tenfold decrease in cost.
Electrical and optical integration
In this project, CITC is responsible for the electrical and optical integration of the SPAD sensor. CITC will develop the packaging concept, which consists of mounting on an interposer using flip chip and low-loss optical coupling between SPAD sensor and glass optical fiber. CITC will assemble multiple prototypes that are ready for integration into the detector modules.
The results of the QuLight Detection project strengthen both the knowledge base and the economic position of the eastern Netherlands. In doing so, we create a robust environment for high-tech innovation and collaboration with industry.
