The microscopic origins of charge noise in solid-state qubits

An exploration of surface charge noise, drift-diffusion dynamics, and how fluctuating surface states decohere solid-state quantum devices. Understanding these microscopic origins is key to engineering longer-lived qubits.

What quantum sensing taught me about measurement

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.
