Quantum memory is the key element of quantum repeater, long distance quantum communication and quantum network. Usually, hot atoms, cold atoms, trapped single atom and Bose-Einstein Condensate can be used as quantum memory. From the year of 2008, solid state memory based on rare-earth ion doped crystal becomes one of the most promising quantum memories.
