Overview of Academic Research
Dr. Yuan Xu is primarily engaged in fundamental scientific research in the fields of quantum computing and quantum information physics, with multiple innovative achievements in quantum control, quantum error correction, and quantum metrology with superconducting quantum circuit systems.
His major achievements include: 1) Realizing quantum control and real-time repetitive quantum error correction for logical qubits encoded in bosonic modes and extending the storage lifetime of quantum information beyond the break-even point, which demonstrates the quantum error correction advantage and represents a key milestone towards practical fault-tolerant quantum computation; 2) Efficiently generating large Fock states with up to 100 photons and achieving quantum-enhanced metrology approaching the Heisenberg limit, which promises practical applications of quantum precision measurements; 3) Developing and implementing quantum control methods with high fidelity, high robustness, and high scalability for superconducting qubits, laying an important technical foundation for the future large-scale superconducting quantum processors.
These research findings have been published in journals such as Nature, Nature Physics, and Physical Review Letters. One work was selected as one of the "Top 10 Scientific Advances in China 2023" by the National Natural Science Foundation of China.
