Implementation of optical approaches
in microwave quantum memory systems

A reliable quantum memory system is now actively searched for among different types of solid state systems. In particular, rare-earth doped spin ensembles, which possess favourable transitions in optical and microwave ranges, are promising candidates.

The current project aims at developing a quantum memory system based on rare-earth spin ensembles. Such quantum memory elements should work at zero magnetic field at ultra-low temperatures. The major task of the project is to implement optical techniques, such as spectral hole burning and frequency comb, into the microwave regime.

Experiments will be performed at temperatures below 1K in a dilution refrigerator at zero magnetic field.
