In this work, we study how we can simulate the quantum sine-Gordon (qSG) model using superconducting quantum circuits. We describe our circuit conﬁguration and demonstrate why it reproduces the qSG and how to simulate it. Our ﬁnal result is the comparison between the simulated energy spectrum of the circuit and the lightest breather state energy, which are expected to map to each other in the continuum limit. We ﬁnd a reasonable agreement between our simulations and the exact result, even though we were limited by diﬀerent reasons. Finally, we propose a roadmap to improve the results
