Project Description

The goal of this project is the realization of integrated nanophotonic circuits enabling the addressing of qubits for industrial quantum sensors. Such systems are to be employed as room temperature ultra-sensitive magnetometers in the fields of geological exploration, defense, navigation, medical imaging, and for the development of quantum computers. This embodies a pioneering quantum technology to be brought early to the market and adopted on a large scale.
This funded fellowship project is part of the Canadian National Quantum Strategy and the Quebec Quantum Innovation Zone. Our team at the Interdisciplinary Institute for Technological Innovation (3IT) is developing impactful and practical solutions in close collaboration with SB Quantum, the National Research Council of Canada, the MiQro Innovation Collaborative Centre, the Quantum Institute (QI) and the National Institute for Optics.
Your task will be the large-scale commercialization of ultra-sensitive magnetometry nanodevices utilizing optically detected magnetic resonance (ODMR) technology. The conclusion of this postdoctoral internship will have a significant impact for the research partners and the quantum industry in Canada at large: The selected individual will be responsible for ensuring the quality of the spin qubit ensembles used in commercial sensors. The researcher will have the opportunity to thrive in the 3IT laboratories and the Quantum FabLab to develop optoelectronic metrology processes:
• Photoluminescence and ODMR characterizations of photonic nanostructures at T=300K and 4K.
• Mapping of quantum decoherence times.
• Quantification of integrated microwave circuits.
• Data analysis and establishment of industrial protocols for quality monitoring.

Work Supervision:
The project will be conducted in collaboration with Dr Dominic Lepage and Pr Dominique Drouin. The selected individual will interact regularly with all collaborators and will conduct most of the work both at the 3IT and QI. The candidate will benefit from an exceptional research environment where students, professionals, teachers, and industry experts closely collaborate for the advancement of future technologies.

Desired Profile:
The desired candidate should have a strong academic record, a PhD in a related field of physics or engineering, hands-on laboratory skills, a sense of creativity, strong adaptability, and an interest in research for the development of optics/photonics/quantum sciences. Experience with optical benches, optical system design, micromanipulation, or radiofrequency technologies will be assets.
Because the research project involves sensitive technology, the applicant should not be affiliated with any of the countries where Canada is imposing sanctions. (see additional link)
 Proficiency in French communication is a plus.
Documents to provide: Cover letter, curriculum vitae and the contact information of two individuals familiar with your work.
