Abstract

Placing an ensemble of 106 ultracold atoms in the near field of a superconducting coplanar waveguide resonator with a quality factor Q~106, one can achieve strong coupling between a single microwave photon in the coplanar waveguide resonator and a collective hyperfine qubit state in the ensemble with geff/2p~40kHz larger than the cavity linewidth of /2p~7kHz. Integrated on an atomchip, such a system constitutes a hybrid quantum device, which also can be used to interconnect solid-state and atomic qubits, study and control atomic motion via the microwave field, observe microwave superradiance, build an integrated micromaser, or even cool the resonator field via the atoms.
