Figure 1: Scheme of the photonic waveguide used by Kim
et al. [4]. The waveguide is an array of identical microwave resonators paired to form an
A-
B lattice (red and blue, respectively). In the topological phase, the waveguide has edge modes, whose wave functions (red and blue) extend in only one direction and over the sublattice comprising only one type of resonator (
A or
B). Qubits (represented with atom symbols) are coupled to each resonator. At the center of the waveguide, a qubit coupled to a site
A resonator (indicated by the arrow) creates a bound state (purple) that extends to the left and only couples to ....
