Single electrons on solid neon as a solid-state qubit platform

First coherent circuit-QED realization of a single electron trapped above solid neon. It demonstrated $g/2\pi =3.5\mathrm{MHz}$ strong electron-photon coupling, microwave control, dispersive readout, $T_1=15\mu \text{s}$, and Hahn-echo coherence $T_2^{\mathrm{echo}}=220\mathrm{ns}$.
