Towards single atom state readout of Rb atoms trapped in solid neon.

In prior work, we studied the optical and spin coherence properties of Rb atoms trapped in solid neon. Working with ensembles, we have demonstrated their ability to sense nearby Ne-21 spins inside the matrix and successfully performed NMR spectroscopy of Ne-21. By scaling down to single-atom measurements, we aim to use a single Rb sensor atom to perform NMR spectroscopy of single nuclear spins co-trapped inside the neon matrix. Progress towards this goal will be discussed.
