"Quantum many-body effects and quantum engineering in artificial atomic systems"

Abstract:

Artificial atomic systems can be architectured in solid -state quantum devices. Given the controllability in the coupling and the parameter regime novel quantum effects can be explored in such devices. In this talk, we will first present a circuit QED scheme where a Quantum Ising chain is coupled with a microwave resonator. We show that sudden switchings between the ferromagnetic phase and the paramagnetic phase as well as a bistable regime can be observed. Second, we will present a scheme for the determinisitc generation of entangled photon pairs in a resonator array. The resonators form a Jaynes-Cummings Lattice and we exploit the Kerr nonlinearity to generate entangled photons.
