Abstract:
The multimode superconducting parametric cavity has proven to be a powerful and versatile system for producing nonclassical states of light in the microwave regime. Utilizing its ability to realize nonlinear and multimode Hamiltonians, we can produce strongly correlated propagating signals from the cavity at different frequencies including entangled photons. In particular, we observe the generation of photon triplets using a cubic Hamiltonian in the cavity under a parametric drive. Furthermore, using a non-Gaussian entanglement witness, we are able to verify the genuine tripartite entanglement of these photon triplets.
