Abstract

Quantum simulation is traditionally conducted in artificial quantum platforms such as ultra-cold atoms, trapped ions and superconducting circuits at extremely low temperatures. In these systems, the energy scale of the lattice parameters is so small that we need to cool down the system to preserve the coherence for enough time to observe the quantum phenomena. By using the strong coupling between atoms and light to build superradiance lattices, which are composed by timed Dicke states in momentum space, we can greatly increase the energy scale of lattice parameters such that quantum simulation can be conducted at room temperature. By exploiting the quantum degree of freedom of light, we can also build lattices in the Fock state space, providing a wealth of topological states that are fundamentally distinct from those in classical topological photonics. In this talk, we will introduce the basic theory of superradiance lattices and Fock-state lattices and their experimental realization. A short history of Chinese physics in the past 100 years is included.
