  "abstract": "Superconducting networks composed of coupled loops with different areas exhibit a rich spectrum of macroscopic fluxoid quantum states. We analyze networks consisting of two types of loops and show that the ratio, $$R$$ , of their areas, expressed as a reduced rational fraction, governs the system’s periodic response, the fluxoid occupation of both large and small loops, and the number of distinct fluxoid states within a single period. Furthermore, we identify a condition on the fraction $$R$$ under which the coupled loops exchange fluxoids at a specific magnetic field. Numerical simulations, based on the “J ² ” model, corroborate these results and reveal how geometrical coupling can produce complex fluxoid configurations, offering potential applications in multistate superconducting memory and flux-based devices.",
