Ji-Yin Wang is currently hired as an associate research scientist of Semiconductor Quantum Computation Group in Beijing Academy of Quantum Information Sciences (BAQIS). He got his B.S. degree from Jilin University in 2013 and got his PhD degree from Peking University in 2018 (supervised by Prof. Hongqi Xu). From 2018 to 2022, he worked as a postdoctoral fellow in QuTech-Microsoft Joint laboratory led by Prof. Leo P. Kouwenhoven. In July of 2022, he joined BAQIS. So far, he has published more than 20 papers in prestigious journals, including Nature, Nature Communications, Science Advances, Nano Letters, Physical Review B, etc. He was elected as overseas high-level personnel and his project is currently funded by National Natural Science Foundation of China. His current research interests include: (1) spin qubits based on semiconductor quantum dots; (2) topological superconductivity based on semiconductor-superconductor hybrids.
