| Abstract: | Quantum memory is one of the fundamental building blocks for quantum networks. It can be used as a synchronization tool that matches various processes within a quantum computer, a tool to convert heralded photons to photons-on-demand and a quantum repeater for long-distance quantum communication. The rare-earth-ion doped crystal has been one of the best candidate systems for quantum memory. Here we report on the state-of-the-art developments in the field of solid state quantum memory, detail current perfomance levels and discuss potential applications of the developed techniques in other fields. |
