TU Delft invites applications for a PhD position in Electrical Engineering to develop scalable cryo-CMOS circuits for interfacing quantum computers and cryogenic single-photon detectors. The candidate will design ultra-low-power, area-efficient readout chains for 1000+ channels, including low-noise amplifiers, time taggers, and data transfer systems, advancing cryogenic circuit performance. Work involves designing prototypes in advanced CMOS technologies, experimental characterization in cryogenic labs, and integration with TU Delft’s photonic quantum computing projects. The position offers international collaboration, high-impact publications, and real-world impact in quantum technologies.
