Rydberg-atom interfaces between photons and superconducting cavities — •Wildan Abdussalam, Daniel Viscor, and Thomas Pohl — Max Planck Institute for the Physics and Complex Systems, Dresden, Germany

Owing to their large polarisability Rydberg atoms hold promise for realising strong coupling between microwave photons and superconducting cavities. Yet, the very same property makes Rydberg states prone to surface noise which has thus far hampered efficient interfacing.

Here, we study the coupled dynamics of a single cavity photon and a strongly interacting ensemble of Rydberg atoms and show that available Rydberg-Rydberg atom interactions can be utilised to overcome this problem. Using realistic noise sources and accounting for additional decay of Rydberg states, we demonstrate that collective photon coupling to interacting Rydberg ensembles provides a promising to noise-resistant quantum interfaces.
