Dissipative stabilization of non-Gaussian entangled states in circuit QED

We analyze a scheme enabling the dissipative preparation and stabilization of entangled Schrodinger cat states in two photonic cavities. Our approach is significantly simpler than previously studied proposals. It requires only linear couplings to a single engineered reservoir (as opposed to nonlinear couplings to two more reservoirs). The remaining ingredients required are purely local: each cavity requires a Kerr interaction, and a local two-photon (i.e.~parametric drive). Our scheme is within the reach of state-of-the-art experiments in circuit QED.
