Research is a lifelong adventure of learning, trying, failing, finding new ways and sharing your knowledge with others.
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 favorable 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.
The focus of my research lies within the rare earth ions as potential building blocks of the quantum-computing infrastructure. The rare earth ions, else lanthanides, are known for their outstanding semi-shielding feature: the 4-f electrons are partially shielded from the external fields by the outer 6s electrons. With this when placed inside a crystal, they can be treated similar to ions in a trap. I investigate their optical and microwave properties and look for methods to implement their advantages for the interest of quantum information field.
