Coherent Spintronics Group

Kyle successfully defended his PhD thesis, “Carbon nanotube electromechanical systems: Non-linear dynamics and self-oscillation”, on April 21, 2020. Congrats Kyle!

His most recent work led to the publication Self-driven oscillation in Coulomb blockaded suspended carbon nanotubes in Physical Review Research.

Earlier work resulted in the publication Probing the non-linear transient response of a carbon nanotube mechanical oscillator in Applied Physics Letters.

Brandon successfully defended his PhD thesis, “Quantum dot devices in silicon and dopant-free GaAs/AlGaAs heterostructures”, on Jan. 18, 2021. Congrats Brandon!

His recent work led to two publications:

Simulated coherent electron shuttling in silicon quantum dots in Physical Review B.

Optimizing lateral quantum dot geometries for reduced exchange noise, submitted for publication.

See other group PhD theses on our Educational Resources page.

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] uwaterloo.ca) for more information.

“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.

Prof. Baugh received a Research Leader Award from the Waterloo Institute for Nanotechnology on June 5, 2018. At left is WIN Executive Director Sushantra Mitra, and at right is VP Research Charmaine Dean.

Prof. Baugh explains how nanoelectronics devices like quantum dots can serve as platforms for scalable quantum information processors to visiting high school student Cassia Attard. (May 1, 2018)

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:

Professor Baugh and the Coherent Spintronics lab were featured recently in an article and video as part of IQC’s Annual Report.

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.
