Project Description

Context : Quantum information technology is currently transiting from academia to industry and the complexity of nanofabrication processes for state-of-the-art devices is growing rapidly. It is now exceeding the research and development capacity of start-up companies or academic research groups. In order to ensure continuous progress of quantum information technology, it is, therefore, necessary to pool the manufacturing efforts of small companies and research groups so as not to restrict the use of this strategic technology to a few large multinational companies. 
The goal of this project is to set up a pilot line for shared nanofabrication of state-of-the-art superconducting circuits in Canada. The project is based on a close collaboration between experts in superconducting quantum circuits at Institut Quantique (IQ) of Université de Sherbrooke (UdeS) and experts in micro- and nanofabrication at 3IT of UdeS where the transition to shared manufacturing has already taken place. The 
industrial partner CMC Microsystems, an expert in the mutualization of processes and tools for the Canadian academic and industrial world, will ensure that the project corresponds to the needs of the market. Equipment manufacturers Angstrom Engineering and Raith will contribute their expertise in thin film deposition and e-beam lithography to the project which will in turn help them to optimize their tools for quantum systems. Theresults of this project will be used directly by the industrial partner Nord Quantique, a start-up company in Sherbrooke that manufactures superconducting quantum circuits

Main tasks
• Development of a state-of-the-art circuit integration by combining the best passive (resonators) and active (Josepshon junctions) together during the course of the project.
• Supervision of students (interns, masters, doctorate)

Required profile
• Specialisation in physics, electrical engineering, quantum sciences and engineering
• Strong taste for design, experimental work in clean rooms, research and development
• Knowledge of the realization of superconducting quantum circuits
• Experience in thin film vacuum deposition and their usual characterizations.

Supervision & work environment: The postdoc will be realized under the direction of Pre. Eva Dupont-Ferrier. The work will be mainly carried out at the Quantum Institute (IQ) at the Interdisciplinary Institute for Technological Innovation (3IT) and of UdeS. IQ is a state-of-the-art institute whose mission is to invent the quantum technologies of tomorrow and transfer them to the industry. 3IT is a unique institute in Canada, specializing in the research and development of innovative technologies for energy, electronics, robotics and health.
