Scheme of a Josephson parametric amplifier (JPA). The field outside the resonator interacts with the resonator mode with a coupling rate k. The resonator mode is evolving under the squeezing Hamiltonian with a coupling χ. The losses are taken into account by introducing an environment mode ĥ, and let it interact with the resonator mode with a coupling rate γ.
