SUMMARY:Analog Quantum Simulation of Topological Lattice Models with a Parametric Cavity
DESCRIPTION:Chris Wilson, IQC, University of Waterloo\n\n\n\nThere has been a growing interest in realizing quantum simulators for physical systems where perturbative methods are ineffective. The scalability and flexibility of circuit quantum electrodynamics (cQED) make it a promising platform to implement various types of simulators, including lattice models of strongly-coupled field theories. Here, we use a multimode superconducting parametric cavity as a hardware-efficient analog quantum simulator, realizing a lattice in synthetic dimensions with complex hopping interactions. The coupling graph, i.e., the realized model, can be programmed in situ. The realization of complex-valued hopping interactions further allows us to simulate, for instance, gauge potentials and topological models. As a demonstration, we simulate small realizations of paradigmatic topological models including the bosonic Creutz ladder and SSH model. We characterize the lattice with scattering measurements, reconstructing the experimental Hamiltonian and observing important precursors of topological features including nonreciprical transport and Ahranov-Bohm caging. This platform can be easily extended to larger lattices and different models involving other interactions.\n\n \n \n
