Figure 1: Jaynes-Cummings-Hubbard lattice with time-reversal symmetry breaking. In this scheme, atom-cavity interactions from superconducting qubits in stripline cavities give rise to an effective particle-particle interaction. Photon hopping between the stripline cavities is via a Josephson ring circuit, as shown in Fig. 2.
