Author(s): F. Albarrán-Arriagada, L. Lamata, E. Solano, G. Romero, and J. C. Retamal
We propose a superconducting circuit platform for simulating spin-1 models. To this purpose we consider a chain of $N$ ultrastrongly coupled qubit-resonator systems interacting through a grounded superconducting quantum interference device (SQUID). The anharmonic spectrum of the qubit-resonator syst...
