The project Next-generation photonic source to enable quantum remote sensing and communications will use cutting-edge semiconductor device engineering to develop novel, on-demand sources of single photons. These sources will have unique capabilities, such as tunability between one- and two-photon emission, and can be scaled to on-chip arrays. This project also includes Baugh’s co-PIs Dr. Michael Reimer, faculty member at IQC and professor in the Department of Electrical and Computer Engineering; Dr. Zbig Wasilewski, a professor in the Department of Electrical and Computer Engineering; and Dr. Francois Sfigakis, a research associate at IQC; as well as partnerships with Defence Research and Development Canada, the National Research Council Canada, and General Dynamics Land Systems - Canada.

The project Towards large-scale spin qubit quantum computers: simulation, modeling and experiment is led by Dr. Lan Wei, with Baugh and Dr. Youngki Yoon as co-PIs. The project is in partnership with NanoAcademic Technologies Inc. It aims to advance the state of the art in silicon quantum computing devices based on electron spin qubits.

Annelise successfully defended her thesis, entitled “Development of III-V Semiconductor Surface Quantum Wells for Hybrid Superconducting Device Applications”, on Jan. 23, 2024. Congratulations Annelise!

Annelise’s work has focused on the development of InAs and InSb two-dimensional electron gas systems as platforms for topological qubits. She has worked in close collaboration with the QNC-MBE group of Prof. Wasilewski and with Dr. Francois Sfigakis in our group. Her original contributions have resulted in a first-author publication in Appl. Phys. Lett. 122, 012103 (2023) as well as another forthcoming paper.

We have several openings for Masters and PhD students to begin in Fall 2024. Students will engage in cutting edge research on semiconductor-based quantum devices. Key projects include:

• Development of scalable spin qubit processors in silicon. Please see this link for more details!
• Next-generation quantum light sources using tailored semiconductor nanoelectronic devices. Please see this link for more details!

If you are interested in this field and have a background in Physics, Engineering Physics, Chemistry or Electrical Engineering, please contact Prof. Baugh (baugh@uwaterloo.ca).

Two postdoctoral positions are open for an exciting multidisciplinary project at the intersection of quantum transport and quantum optics. This is a collaborative project between Prof. Baugh's group and the group of Prof. Michael Reimer, both at the Institute for Quantum Computing. Please see this link for details, and forward to anyone who may be qualified and interested in a position!

Here is an interview with John Donohue, Scientific Outreach Manager at IQC, regarding our recent work developing InSb heterostructures for topological quantum computing and other applications. It features work led by PhD student Annelise Bergeron, with many contributions from Dr. Francois Sfigakis, and in collaboration with the MBE group of Prof. Zbig Wasilewski.

The Silicon quantum electronics workshop held near Sherbrooke, QC, was a great meeting with many impressive results in the area of silicon spin qubits. Bohdan presented his talk on simulating small QI processors and a novel method of pulse design.

Sean successfully defended his PhD thesis, entitled "Scanning tunneling microscopy of electrically driven phase transitions in a charge density wave material" on March 3, 2022. His PhD is in Chemistry with a Quantum Information specialization.

Here is an animation based on our 2019 paper "Network architecture for a topological quantum computer in silicon".

Congratulations to Bohdan Khromets and Alex Currie for both successfully defending their MSc theses during the Fall 2021 term!
