Overview of Academic Research
Aiming to realize a semiconductor quantum computing prototype, Hai-Ou Li has long been dedicated to experimental research on the fabrication, encoding, manipulation, and scaling of semiconductor qubits. This has yielded a series of groundbreaking achievements: Fabricated domestically designed semiconductor quantum chip materials and quantum dot structures, mastering core technologies for semiconductor quantum chip fabrication and manipulation. Utilized key technologies to fabricate various complex semiconductor qubit circuits, successfully achieving a single-qubit ultrafast universal gate, a two-qubit controlled-NOT (CNOT) gate, and a three-qubit Toffoli gate. This established a quantum computing logic gate library based on semiconductor quantum dots. Designed and fabricated silicon-based semiconductor spin qubits, realizing efficient control of silicon-based spin lifetimes, ultrafast manipulation of hole spin qubits, and a two-spin-qubit SWAP gate. Furthermore, achieved strong coupling between superconducting resonator microwave photons and quantum dots, as well as long-range coupling between two quantum dots. Published over 100 SCI-indexed papers, including more than 50 as first or corresponding author in prestigious journals such as Nature sub-journals and Physical Review Letters. Filed and obtained over 30 patents. Led/Executed research projects including: National S&T Innovation 2030 Major Project Topics, Key Project Topics of NSFC Major Research Plan， NSFC General Program Projects et. Related research achievements were awarded the 2018 First Prize of Anhui Provincial Science and Technology Award.
