"tailored resonator geometry selects wavelengths at which photons can/ cannot pass... up to 100 high-quality coupled cavities (arranged in repeating pattern where each cavity interacts with neighbors) in compact array where each cavity miniaturized, unwanted disorder in resonant microwave frequencies minimized using superconductor niobium nitride relying on high kinetic inductance...  mimics photonic topological insulator guiding light along its edges in controlled/ unusual way... future: coupling to artificial atoms"
