This project aims to develop quantum light sources, and demonstrate their use in quantum applications including computing, sensing, and communications. The quantum light sources are based on the hybrid integration of quantum dot compound semiconductors with the silicon integrated photonics platforms. These light sources will use quantum dot lasers with stabilization circuits, and will pump non-linear circuits to create non-classical light sources for photon pair generation or squeezed state generation. The quantum applications will be in quantum computing (quantum photonic neural networks), quantum communication (quantum key distribution, QKD), and quantum sensing (quantum-enhanced LiDAR and gyroscopes). The proposal brings together several academic and industrial partners who contribute key expertise to deliver on this project. Academic partners will contribute to chip design (UBC, Laval, Queen's), fabrication and hybrid integration (UBC), quantum communications research (UBC), quantum LiDAR research (Laval), and quantum photonic neural network research (Queen's). The industrial partners will contribute to the modelling of the light sources and application circuits, and testing the quantum light sources. A not-for-profit partner will contribute design review and design aggregation. Additional collaborators will design and test photonic integrated circuits that utilize the quantum integrated circuits (University of Toronto, McGill University, UBC, Sydney, U Florida, INRS, Ottawa). We will collaborate with the European organization ePIXfab (led by Gent University), to organize international workshops on III-V silicon integration. We will offer training workshops and courses for the Quantum BC CREATE Program and in partnership with CMC Microsystems.
