Characterizing the magnetic noise power spectrum of dark spins in diamond

New Journal of Physics
The coherence times of solid-state spin qubits are often limited by the presence of a spin bath. Characterizing the spectrum of the local magnetic field fluctuations of the bath is key to understanding spin qubit decoherence.
