Networks of superconducting resonators are promising candidates for the implementation of analog quantum simulators. In this context it is necessary realize a controllable coupling between nearest neighbor resonators. Furthermore, the coupling strength between the resonators has to be larger than the decay rates of the involved resonators. Here, we present experimental data from two microwave resonators which are coupled via an RF-SQUID. The coupling can be turned on and off by applying an external magnetic field, which changes the operation point of the RF-SQUID. Making use of chains of DC-SQUID intersected nonlinear resonators, these devices may pave the way to simulate bosonic many body Hamiltonians in the driven-dissipative regime.
