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.

Optical nanofiber (ONF)-atom configurations can serve as quantum nodes. We provide time-delayed feedback for such nodes using Fiber-Bragg-Grating (FBG) mirror and record the arrival time of photons, emitted by the same atoms.

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.

We propose a time-delayed feedback control scheme for open quantum systems that can dramatically reduce the time to reach steady state. No measurement is performed in the feedback loop, and we suggest a simple all-optical implementation for a cavity

The Dicke model is of fundamental importance in quantum mechanics for understanding the collective behaviour of atoms coupled to a single electromagnetic mode. In this paper, we demonstrate a Dicke-model simulation using cavity-assisted Raman transit

Large-scale quantum networks could allow a wide variety of applications in quantum computing and simulation. Here we demonstrate the operation of a single node for use in such a network. We employ a ring geometry all-fiber cavity system for cavity qu

Resonant excitation of multi-photon transitions in one-atom cavity QED, from the ground state to an excited dressed state, induce an additional semiclassical Rabi splitting. This “dressing of the dressed states” arises from a multi-photon blockad

Beyond traditional nonlinear optics with large numbers of atoms and photons, qualitatively new phenomena arise in a quantum regime of strong interactions between single atoms and photons. By using a microscopic optical resonator, we achieved such int

We investigate a two-way cascaded cavity QED system consisting of microtoroidal resonators coupled through an optical fiber. Each microtoroidal cavity supports two counter-propagating whispering-gallery modes coupled to single atoms through their eva
