Superconducting circuitry has recently become a leading technological platform for quantum engineering and quantum information processing. Circuit elements are assembled in ever larger networks, which have reached a development threshold that opens intriguing perspectives for exploring quantum many-body phenomena. This objective can even be taken further to design quantum matter with new properties that are usually not found in nature.
After introducing the main circuit elements, I will particularly discuss tunable and nonlinear couplers and their applications. These can lead to a novel density ordering in quantum lattice systems that has been observed in a recent experimental implementation. I will then explain how these couplers can be used to engineer a large variety of spin-spin interactions, making such systems an ideal platform for simulating quantum magnetism and topological order.
