Description

Rydberg atoms --- large atoms with a highly excited, loosely bound electron --- may enable hybrid quantum systems, combining the long coherence times of atomic systems with the strong interactions of solid-state devices. However, this will require atoms to be located near a heterogeneous surface with exposed metal electrodes and dielectric insulators, which are sources of uncontrollable and unwanted electric fields. With this motivation, we have measured both the static [1] and time-varying [2] electric fields near the heterogeneous metal-dielectric surface of an atom chip using cold Rydberg atoms. We have also developed a technique for reducing the influence of dc and low-frequency electric fields on Rydberg atom transitions, while retaining their sensitivity to high-frequency resonant fields [3].
