Abstract

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.

Generation of single photons of alternating polarization

Tatjana Wilk, Holger Specht, Axel Kuhn +1 more

We present first results of single-photon generation from an atom-cavity system, where Raman transitions are driven between Zeeman sublevels. The process results in photons with alternating polarisations and requires no repumping.

Theory of Raman transitions in cavity QED

A. David. Boozer

We present two schemes for driving Raman transitions between the ground-state hyperfine manifolds of a single atom trapped within a high-finesse optical cavity. In both schemes, the Raman coupling is generated by standing-wave fields inside the cavity, thus circumventing the optical access limitations that free-space Raman schemes must face in a cavity system. These cavity-based Raman schemes can be used to coherently manipulate both the internal and motional degrees of freedom of the atom, and thus provide powerful tools for studying cavity quantum electrodynamics. We give a detailed theoretical analysis of each scheme, both for a three-level atom and for a multilevel cesium atom. In addition, we show how these Raman schemes can be used to cool the axial motion of the atom to the quantum ground state, and we perform computer simulations of the cooling process.

A Scheme for Generation of Multi-Atom Entangled W State in Cavity QED

Hong‐Mei Zou

This article discusses an alternative scheme to generate a multi-atom entangled W state in cavity QED via Raman transitions.The present scheme does not involve cavity-photon population during the operation and thus is insensitive to the cavity decay.On the other hand,we have also indicated that the scheme is easy to implement from the experimental point of view.

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.
