Abstract: Recent experiments on superconducting qubits and resonators have demonstrated excellent connectivity, long decoherence times and strong coupling in the microwave regime. Such quantum devices provide a powerful platform for investigating quantum coherence and many-body effects, besides being a promising candidate for scalable quantum computing. In this talk, I’ll present our recent works on superconducting analog quantum emulators, in particular, a multi-connected Jaynes-Cummings model that demonstrates a reentrant behavior from a superfluid state to a Mott-insulator state.
