Title:

Quantum optics using atomic arrays 

Abstract:

Our conventional theories of the quantum interactions between light and atomic media tend to treat the atoms as a smooth macroscopic medium, ignoring the possibility that the dynamics might depend strongly on microscopic configurations and disorder. Within classical optics, however, it is well-known that the details of spatial configurations of scatterers — and the associated multiple scattering and interference of light — can give rise to important new phenomena and control, ranging from Anderson localization to photonic crystals and phased array antennas. We discuss our recent efforts to advance a theory of quantum multiple scattering of light. We also show how multiple scattering can be harnessed as a powerful resource, including the possibility to realize polynomially or exponentially better error scalings for applications such as quantum memories of light and photon-photon gates, as a function of system resources.
