Description
<p>We have observed extremely strong coupling between a superconducting flux qubit and a microwave LC resonator. The coupling energy is larger than the energies of the bare qubit and photons. The observed energy spectra are well described by the Rabi model, and they agree with selection rules that reflect the symmetry of the circuits. All our observations indicate the realization of an entangled ground state. Finally, the relation with the superradiant quantum phase transition is discussed.</p>
