点击翻译按钮获取中文摘要

We propose to design highly-optimized light sources for quantum computing applications. The light sources will be compatible withphotonic integrated circuit (PIC) processing technologies, in order to be directly integrated with modern optical signal processingtechnologies. The challenges to be overcome in this project include the very weak nonlinear response of most transparentmaterials, the design of structures that are tolerant to fabrication imperfections, ensuring that the design can be fabricated in acost-effective manner, etc. The collaboration between the University of Toronto and Xanadu will be very effective in producing ahigh-quality light source, since the University will bring expertise in the design of high-performance nonlinear optical devices, whileXanadu has the necessary resources and expertise to fabricate quantum information processing devices, and an understanding ofthe practical market needs of these high-tech solutions. Through this collaboration, we expect to lower the cost of quantumcomputing solutions, opening this important new area of technology to a wider range of customers.
