Feng Jinxia, female, holds a Doctor of Science degree, is a professor and a master's supervisor. Graduated from Shanxi University in 2003, majoring in Physics (National Base), and obtained a Bachelor of Science degree. Graduated from the Institute of Optoelectronics/State Key Laboratory of Quantum Optics and Photonic Quantum Devices, Shanxi University in 2008, with a Doctor of Optics degree. From 2009 to 2010, I conducted postdoctoral research in the research group of Professor Claude Fabre in the Kastler-Brossel laboratory at the Sorbonne University in Paris, France. Since 2011, I have been working at the Institute of Optoelectronics/National Key Laboratory of Optical Quantum Technology and Devices, Shanxi University.
The work mainly focuses on the development of all-solid-state laser technology and continuous variable non-classical light sources, as well as their application research in fields such as quantum information processing and quantum precision measurement. He has presided over and participated in more than ten scientific research projects, including those funded by the National Natural Science Foundation of China, the National Key Research and Development Program, and the National Major Scientific Instrument and Equipment Development Special Project of the Ministry of Science and Technology. In Phys. Rev. Lett., Appl. Phys. Lett., Opt.Lett. More than sixty papers have been published in academic journals and over twenty domestic and foreign invention patents have been authorized. The research achievement "Preparation, Manipulation of Quantum States in Light Fields and Their Application in Quantum Information" won the second prize of Natural Science of Shanxi Province and was selected as an outstanding young talent of Shanxi Province's "Sanjin Talents" program. Teaches undergraduate courses such as "Optics" and "Nonlinear Optics".
