Study of the electromagnetically induced transparency in the rare-earth spin ensembles in the microwave regime
A reliable quantum memory system is being 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 this project is to implement the electromagnetically induced transparency, widely used in optics, into the microwave regime. We are looking for a highly motivated master student joining this project. Within your thesis, you will couple the spin-ensembles to the superconducting transmission lines and will manipulate the spin-states with microwave pulses. You will learn about the nature of the electromagnetically induced transparency and its application in quantum memory. Within the project, you will get hands on experience in synthesizing microwave pulses; how to measure the time responses of the spin-systems and how to operate such systems at cryogenic temperatures.

Time-domain study of the dynamics of microwave spectral holes in the rare-earth spin ensembles
A reliable quantum memory system is being 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 this project is to implement the spectral hole burning technique, widely used in optics, into the microwave regime. We are looking for a highly motivated master student joining this project. Within your thesis, you will address questions regarding the dynamics of spectral holes in the absorption profiles of the rare-earth spin ensembles in the microwave regime. You will couple the spin-ensembles to the superconducting transmission lines and will manipulate the spin-states with microwave pulses. Within the project, you will learn about dynamics of the spin-states, how to synthesize microwave pulses, measure the time responses of the spin-systems and how to operate such systems at cryogenic temperatures.
