The School of Physics of Zhengzhou University has made positive progress in the study ofmicrowave mode cooling at room temperature and cavity quantum electrodynamics effect with nitrogen vacancy center in diamond.The relevant research results were published in npj Quantum Information, an internationally authoritative academic journal, with a paper entitled Microwave Mode Cooling and Cavity Quantum Electrodynamics Effects at Room Temperature with Optically Cooled Nitrogen-vacancy Center Spins.Zhang Yuan, a young teacher from the School of Physics of Zhengzhou University, is the first author and corresponding author. Wu Qilong, a 2022 doctoral student, is the co-first author. Professor Shan Chongxin from Zhengzhou University and Professor Klaus Mølmer from Aarhus University in Denmark are the co-corresponding authors.
