The investigation of many-body Hamitonians is relevant to understand collective quantum behavior in solid state physics. However, solving these many-body Hamitonians can be challenging on a classical computer. For this reason, quantum simulations are an attractive approach to simulate such complex Hamitonians with experimentally easily accessible and well-controlled systems. In our experiment, we use superconducting circuits to take the first steps towards this direction. More precisely, we characterize chains of up to four coupled transmission line resonators in a scalable layout. After introducing nonlinearities in the form of Josephson junctions and scaling to longer chains, our system can become a quantum simulator for Bose-Hubbard-type Hamitonians.
