Overview of Academic Research
Professor Dapeng Yu has conducted research in the fields of quantum computing, quantum state control, and scientific instrument development, and has achieved the following important results:
In the field of quantum computing, professor Dapeng Yu leads a superconducting quantum computing research team that, for the first time, demonstrated that the quantum error correction break-even point can be exceeded by approximately 16% using real-time repetitive error detection and discrete-variable bosonic encoding. This result was recognized as one of the “Top Ten Scientific Advances in China” in 2023. In distributed quantum computing, the team developed an ultralow-loss interconnect architecture linking 20 qubits across five physically separate superconducting quantum chips, achieving 99% fidelity in inter-chip quantum state transfer. This result was selected as one of the “Top Ten Advances in Chinese Chip Science” for 2023. The team also achieved the longest-distance superconducting chip-to-chip quantum entanglement reported to date, spanning 64 meters. Additional progress includes the full calibration and topological edge transport demonstration of a 36-qubit chip, as well as the successful development of a 3D flip-chip packaging process for a 66-qubit superconducting processor, enabling quantum error correction experiments. In addition, the research team has independently developed a full-stack superconducting quantum electronics chain—including microwave measurement and control systems, cryogenic low-noise amplifiers, and other key components—establishing a technological foundation for the autonomous construction of large-scale quantum computing facilities capable of supporting tens of thousands of qubits.
In the field of quantum state control, professor Dapeng Yu led a research team to prepare silicon and metal oxide nanowire materials internationally, systematically studied novel physical properties such as luminescence and quantum transport of semiconductor nanowires, and for the first time revealed the modulation law of strain gradient on the bandgap, electronic structure, and especially exciton dynamics of semiconductor materials. The gate voltage control of Majorana zero energy mode was achieved in the Dirac semimetall nanowire system. Dapeng Yu also led the large-scale preparation and major application research of low dimensional quantum materials, and pioneered the development of high current density field emission current sources for semiconductor nanowire arrays. He achieved the controllable preparation of large-area single crystal graphene with a size of meters, and led the manufacturing of a single crystal copper foil library with the largest A4 paper size and over 30 high index crystal facets.
In the field of scientific instruments development, as the chief designer, professor Dapeng Yu led a research team to undertake the indigenization of several chokepoint equipment in the semiconductor/microelectronics and quantum information technology fields, such as electron beam lithography systems and ultra-low temperature dilution refrigerators. His team successfully developed a 50 kV electron beam lithography machine with core technical indicators reaching the international level of similar products. In terms of dilution refrigeration machines, Dapeng Yu’s team overcomes the processing technology difficulties of key components such as continuous heat exchangers and silver powder sintering heat exchangers, and independently built a domestically produced dilution refrigeration machine prototype, including the indigenization of pulse tube cooling heads.
