Optical and spin-coherence properties of rubidium atoms trapped in solid neon
Abstract
In this work, we measure the properties of ensembles of rubidium atoms trapped in solid neon that are relevant for use as quantum sensors of magnetic fields: the spin coherence of the trapped atoms, and the ability to optically control and measure their spin state. We use the rubidium atoms as an AC magnetometer — by employing an appropriate dynamical decoupling sequence — and demonstrate NMR detection of Ne atoms co-trapped in the neon matrix.
