Now hiring: graduate student positions available

We are seeking highly motivated students for MSc or PhD positions to start Fall 2019. Projects are available on several semiconductor nano-electronics platforms:

  • silicon quantum dots for scalable spin qubits
  • single/entangled photon source for quantum illumination
  • high spin-orbit 2D electron gas materials for topological quantum states
  • carbon nanotube nano-mechanical resonator for force detection

Please contact Prof. Baugh (baugh [at] for more information.

New paper on silicon quantum computing architecture is published

“Network architecture for a topological quantum computer in silicon” has been published in IOP’s Quantum Science and Technology journal. We introduce a design for a large-scale surface code quantum processor based on a node/network approach for semiconductor quantum dot spin qubits.

Major funding for quantum light source project announced

Our $2.7 million project with Defence Research and Development Canada was announced on Thursday, April 12 by Honourable Bardish Chagger, Minister of Small Business and Tourism and our local Waterloo MP, at  a press conference hosted at RAC. It is a collaborative project, headed by Jonathan Baugh, with co-PI’s Prof. Michael Reimer and Prof. Zbig Wasilewski. Dr. Francois Sfigakis is the project manager. He is a Research Assistant Professor (Chemistry) working in Baugh’s group.


The event was followed by tours of the Reimer and Baugh labs. In the picture above, MP Bardish Chagger and MP Raj Saini can be seen holding semiconductor chip samples. The story was also covered in local and national media. Here are links to some stories:

Postdoc positions available

Two postdoctoral research positions are now available in our group at the Institute for Quantum Computing, University of Waterloo. We anticipate two-year appointments, with the possibility of a third year, contingent on performance and funding. These appointments may begin as early as Fall 2017. Excellent candidates are sought with an experimental background in semiconductor devices, nano- and micro-fabrication, and cryogenic transport measurements. A PhD in Physics, Engineering Physics, Chemistry or closely related fields is required. Experience with device modeling using finite element methods is desirable, but not strictly required. Knowledge of techniques in classical/quantum optics and spectroscopy is also helpful. We are equipped with state-of-the-art laboratories for device fabrication and measurement.

The first project involves the fabrication and measurement of lateral quantum dots and gated P-N junctions in III-V semiconductor heterostructures, e.g. GaAs or InGaAs two-dimensional electron gases. Applications of interest include novel solid-state quantum light sources and electron (or hole) spin qubits. Strong prior experience with standard micro-fabrication tools and methods is necessary. Familiarity with gate-defined quantum dots and high-frequency techniques (e.g. fast gating) is highly desirable. The project is in collaboration with Engineering-based researchers who are experts in quantum optics and materials growth. The entire team consists of several postdoctoral and graduate members, whom the researcher will work alongside.

The second project is to develop infrared photodetector technology based on III-V nanowires. It will involve fabrication of, and experimentation on, single-wire and ensemble-wire photo-transport devices, both at room temperature and at cryogenic temperatures. Knowledge of semiconductor device modeling and optical spectroscopy techniques are desirable. The researcher may also contribute to other nanowire device initiatives, such as fundamental transport studies in low dimensions, quantum dot spin qubits, and topological states in solid-state systems. The project is in collaboration with nanowire growth experts at McMaster University. The researcher will work alongside another postdoctoral researcher and 2-3 graduate students.

Interested candidates please contact Prof. Baugh, baugh[at]

Prof. Baugh at OCE Discovery


Prof. Baugh attended the OCE Discovery technology fair on May 9 in Toronto, and presented his work on “Nanowire-based infrared photodetectors” to the global Chief Technology Officer of Lockheed Martin, Dr. Keoki Jackson (far left in photo). The work is in collaboration with Prof. Ray LaPierre of McMaster University (far right in photo), and from our group involves Eduardo Barrera and Greg Holloway.
