QuTech is a multidisciplinary institute at the Delft University of Technology. Qutech’s mission is to explore and develop quantum technologies. In particular, hardware and software for quantum computing and quantum internet applications. This contract aims to acquire a dilution refrigerator for a new experimental lab. This lab’s research focuses on single-photon emitters for quantum networking applications. The primary objective is to procure a robust and reliable system that can cool down research samples to millikelvin temperatures, while providing electrical connections and optical access.
