Optical and magnetic properties of Rb-doped Ne solids

Single-atom quantum sensors require long coherence times and the ability to detect and control the atom's quantum state. We have found that the spin state of Rb atoms trapped in cryogenic neon solids satisfies these requirements, making this system a promising one for magnetometry of materials co-trapped in the matrix and for single-molecule NMR. This poster presents key optical and magnetic properties of Rb atoms in solid Ne, modifications to our apparatus to enable single-atom detection in the matrix, and our current progress towards that goal.
