The Raith electron-beam lithography system is one of the fabrication tools central to our research, available as part of the Quantum-Nano Initiative at Waterloo. A student using the probe station to perform a test of nanowire conductance. Insert of the Oxford VeriCold DR200 dilution refrigerator system. The bottom plate holds the He3-He4 mixing chamber and reaches base temperature. Sequentially, the upper plates are the 80 mK plate, the still plate, the 4 K plate, and the 70 K plate.

Interested in a Masters or PhD project?

Highly motivated students are currently being sought. Group projects involve:

  • Design, fabrication and experimental characterization of semiconductor quantum devices
  • Quantum transport at cryogenic temperatures
  • Theory, simulation and modeling
  • Scalable QC architectures based on spin qubits

Students will gain both hands-on and theoretical experience across Physics, Chemistry, Materials Science and Electrical Engineering. Firm theoretical grounding (especially quantum mechanics), strong experimental aptitude and creativity are key qualities.


Undergraduate 4th year projects

Projects related to our research on quantum information and its implementations are available for CHEM 494 and PHYS 437
