Beschreibung

This thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory.

The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.



Dong-Sheng Ding received his B.Sc. in Physics from Anhui Normal University, China in 2006. He obtained his Ph.D. in optics from the Department of Optics and Optical Engineering of the University of Science and Technology of China in 2015. His major research project in the Prof. Bao-Sen Shi group is quantum memory based on cold atoms. Subsequently, he became an Associate Professor in the same group.
