Abstract:
Quantum memory is very important for the realization of quantum networks. It is the current research front and hot spot in the field of quantum information. Rare earth ion doped solids is very promising material as a candidate quantum storage due to their long coherence time and large in homogeneous broadening. In this review, we first introduce the rare earth doped solid state quantum memory in terms of materials, storage protocols, application, etc. Then we elaborate quantum memory based on atomic frequency comb(AFC), including its mechanism, experimental methods and recent progress. Finally we give a summary and outlook of quantum memory.
Key words:  quantum internet, solid state quantum memory, rare earth ion doped solids, atomic frequency comb
