Project Level: Honours, Masters, Winter/Summer

High quality factor microwave resonators are critical components of quantum computer architectures. Aluminium resonators on silicon are now standard components in these architectures, but the measured quality factors in these resonators is lower than expected. Recent work suggest that the limiting factor for these devices are imperfections at the metal-substrate interface. This project focuses on preparing atomically precise interfaces between Aluminium and Silicon for improved superconducting qubits. Using new equipment housed at CMM, the student will prepare clean Silicon surfaces under ultrahigh vacuum conditions and develop procedures to grow high quality factor resonators. The student will gain experience with ultrahigh vacuum equipment, electron spectroscopy, electron diffraction, and low temperature instrumentation.
