摘要

We propose a scheme for a new artificial atom suitable for constructing quantum simulators of photonic topological models. The design consists of four capacitively shunted Josephson junctions, controlled by an external magnetic flux, in a diamond-shaped configuration. It maintains arbitrary polarization states through two degenerate excited states with mutually orthogonal electric field distributions. Furthermore, we show that a high operating ratio of the Josephson energy to the charge energy suppresses the sensitivity to fluctuating background charges far from the degeneracy points.
