Yuan Xu
Associate Researcher

I have long been devoted to experimental research in the field of quantum information processing based on superconducting quantum circuits and has realized a number of important achievements in the fields of entangling quantum control and quantum error correction of superconducting qubits and bosonic modes. I have published a total of 28 high-level SCI academic papers in journals including Nature, Nature Physics, Physical Review Letters, Nature Communications, Science Advances, etc., of which 7 have been published as first or corresponding author (1 accepted by Nature and 5 published in Physical Review Letters). The total accumulated citations from Google Scholar exceed 1100 with an H-factor of 15. At present, as a project leader, I have been funded by the projects of the Shenzhen Science and Technology Program, the Guangdong Basic and Applied Basic Research Foundation, and the National Natural Science Foundation of China.
