Optical decoherence in Er${}^{3+}$-doped CeO${}_2$ spin qubit platforms

Vrindaa Somjit, Ignas Masiulionis, Gregory D. Grant +7

Erbium ions (Er${}^{3+}$) in cerium dioxide (CeO${}_2$) represent a promising spin-photon interface for quantum communication, but the mechanisms limiting their optical coherence remai…
