Coupled nonlinear cavities provide a versatile testbed to study fundamental light-matter interactions and constitute a generic building block to realize photonic quantum simulators for strongly interacting systems. Their theoretical investigation and experimental realizations have therefore been driven forward in a variety of physical settings. In my talk I will present the implementation of a dissipative Bose-Hubbard dimer in superconducting circuits to achieve quantum limited amplification and to generate frequency entangled microwave photon pairs. Featuring a flexible control over the relevant system parameters, the presented lumped element circuit has also great potential to be used as an elementary cell in larger nonlinear cavity arrays. In contrast to previous implementations of microwave parametric amplifiers our device can be operated both as a bsingle mode squeezer and as a nondegenerate phase-preserving amplifier. In combination with its large achievable bandwidth, tunability and saturation power our device may find broad application in experiments aiming at quantum limited detection – particularly in superconducting circuits.
