Superconducting quantum chips are excellent physical systems for both investigating the foundations of quantum physics and advancing applications in quantum information processing. Their capacity to be designed, fabricated, and operated with relative ease, even when comprising hundreds or thousands of elements, positions them as a leading candidate for the realization of quantum computers. In this talk, I will briefly introduce the basic concepts and background of superconducting quantum chips. After that, I will present the quantum chips we have developed, highlighting two core technologies from a design perspective. The first technology pioneers the investigation of superconducting coupler architectures through layout analysis, while the second one introduces innovative simulation and verification methodologies. Both technologies represent significant advancements toward achieving quantum electronic design automation for superconducting quantum chips.
Lijing Jin obtained the PhD degree in the field of circuit quantum electrodynamics from Université Grenoble Alpes and Centre national de la recherche scientifique (France), followed by 2-year postdoctoral research at Beijing Computational Science Research Center, and extensive 5-year industry research in superconducting quantum computing at the Institute for Quantum Computing, Baidu Research. He was a recipient of Young Scientist Fund Project supported by National Natural Science Foundation of China. During his recent role as a Staff Researcher and Tech Lead at Baidu Research, he had been contributing significantly to the research and development of superconducting quantum chips as well as the quantum control platform Quanlse. In the area of superconducting quantum computing technology, he had filed over 80 patent applications, and 50 of them have been granted by the Intellectual Property Office of China, USA, Japan, and Australia.
