Solid-state optical quantum memory based on rare-earth ion-doped crystals

We study the generation, storage and characterization of different quantum states of light in the solid-state  optical quantum memory. The memory consists of an ensemble of rare-earth ions doped in a crystal at cryogenic temperature with a temporal/spectral multimode capability.  Using novel crystalline material we also demonstrate simultaneously induced clock transitions for  microwave and optical domains with solid-state electronic spins. This is one of the ingredients for future broadband optical quantum memories based on spin-wave storage.
