Hands-on experience with optically active spin defects in solids, including for example diamond color centers, SiC defects, rare-earth ions, hBN defect emitters, and related platforms). Experience with optical, electronic, microwave, and RF instrumentation used for laser modulation, photon counting, and/or pulsed spin resonance experiments (AWGs, VNAs, IQ modulators, EOMs, AOMs, time taggers).
