Schemes for Nonclassical Light Generation with a Single Multilevel Atom in a Cavity

A. E. J. Elliott, A. S. Parkins

Raman transitions between atomic sublevels in a continuously-driven, single-atom cavity QED system are explored for the generation of a variety of quantum states of the output light field.

Cavity QED systems for steady-state sources of Wigner-negative light

Alex Elliott, A. S. Parkins

We present a theoretical investigation of optical cavity quantum electrodynamics (cavity QED) systems, as described by the driven, open Jaynes–Cummings model and some of its variants, as potential sources of steady-state Wigner-negative light. We consider temporal modes in the continuous output field from the cavity and demonstrate pronounced negativity in their Wigner distributions for experimentally relevant parameter regimes. We consider models of both single and collective atomic spin systems, and find a rich structure of Wigner-distribution negativity as the spin size is varied. We also demonstrate an effective realization of all of the models considered using just a single 87 Rb atom and based upon combinations of laser- and laser-plus-cavity-driven Raman transitions between magnetic sublevels in a single ground hyperfine state.We present a theoretical investigation of optical cavity quantum electrodynamics (cavity QED) systems, as described by the driven, open Jaynes–Cummings model and some of its variants, as potential sources of steady-state Wigner-negative light.

Steady-State Wigner-Negative Light From a Cavity Coupled To a Driven Multilevel Atom

A. E. J. Elliott, A. S. Parkins

We investigate temporal modes in continuous output light from a cavity QED system in which a single atom undergoes cavity- and laser-assisted, multistep Raman transitions along a ground hyperfine state. Wigner function negativity is predicted.
