Noise resistant coupling between Rydberg atoms and a superconducting cavity via dipole-dipole interactions — •Daniel Viscor¹, Wildan Abdussalam¹, József Fortágh², Antoine Browaeys³, Thierry Lahaye³, and Thomas Pohl¹ — ¹Max Planck Institute for the Physics of Complex Systems, Nöthnitzer Straße 38, 01187 Dresden, Germany — ²Physikalisches Institut der Universitat Tübingen, Auf der Morgenstelle 14, 72076 Tübingen, Germany — ³Laboratoire Charles Fabry, Institut d'Optique, CNRS, Univ Paris Sud 11, 2 Avenue Augustin Fresnel, F-91127 Palaiseau Cedex, France

We theoretically study the coherent exchange of a single photon between a superconducting microwave cavity and a lattice of strongly interacting Rydberg atoms in the presence of local electric field fluctuations plaguing the cavity surface. We show that despite the increased sensitivity of Rydberg states to electric fields, the Rydberg dipole-dipole interaction can be used to protect the system against the dephasing induced by the spurious fields. Using realistic noise models we show that compared to the case with non-interacting atoms, our system exhibits longer coherence lifetimes and larger retrieval efficiency of the photon after storing into the atoms.
