Query: Fluxon-Based Quantum Simulation in Circuit QED   Long-lived fluxon excitations can be trapped inside a superinductor ring,
which is divided into an array of loops by a periodic sequence of Josephson
junctions in the quantum regime, thereby allowing fluxons to tunnel between
neighboring sites. By tuning the Josephson couplings, and implicitly the fluxon
tunneling probability amplitudes, a wide class of 1D tight-binding lattice
models may be implemented and populated with a stable number of fluxons. We
illustrate the use of this quantum simulation platform by discussing the
Su-Schrieffer-Heeger model in the 1-fluxon subspace, which hosts a symmetry
protected topological phase with fractionally charged bound states at the
edges. This pair of localized edge states could be used to implement a
superconducting qubit increasingly decoupled from decoherence mechanisms.
