University of Electronic Science and Technology of China and Shandong University jointly develop a new type of light-atom entanglement chip

The joint team of the University of Electronic Science and Technology of China and Tianfu Jiangxi Laboratory, in cooperation with Shandong University, has successfully developed a light-atom entanglement chip based on erbium-doped lithium niobate crystal waveguides and completed relevant verification for the first time in the world. This new chip will promote the development of long-distance, high-bandwidth quantum entanglement interconnection systems.
