How embedding rare-earth ions (like Erbium) into heterogeneous photonic crystal cavities enables long coherence times and strong light-matter interaction for quantum memories.

Most of my PhD is about making measurements harder — squeezing information out of solid-state systems where the signal is tiny and the noise is everywhere. Rare-earth ions, decoherence in hybrid structures, charge noise at surfaces: the whole field is an exercise in understanding what limits sensitivity, and what you can do about it. These are the notes I'd give a friend about what that training does to the way you think.
