Photon Switching by Quantum Interference
TLDR
In this article, the authors describe a four-state atomic system that absorbs two photons, but does not absorb one photon, but operates at an energy cost of one photon per switching event.Abstract:
We describe a four-state atomic system that absorbs two photons, but does not absorb one photon. As a switch, in the ideal limit, it operates at an energy cost of one photon per switching event.read more

Electromagnetically induced transparency : Optics in coherent media
TL;DR: In this paper, the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments.

Light speed reduction to 17 metres per second in an ultracold atomic gas
Lene Vestergaard Hau,Lene Vestergaard Hau,Stephen E. Harris,Zachary Dutton,Zachary Dutton,Cyrus H. Behroozi,Cyrus H. Behroozi +6 more
TL;DR: In this paper, an experimental demonstration of electromagnetically induced transparency in an ultracold gas of sodium atoms, in which the optical pulses propagate at twenty million times slower than the speed of light in a vacuum, is presented.

Quantum fluids of light
Iacopo Carusotto,Cristiano Ciuti +1 more
TL;DR: In this paper, a review of recent theoretical and experimental advances in the fundamental understanding and active control of quantum fluids of light in nonlinear optical systems is presented, from the superfluid flow around a defect at low speeds to the appearance of a Mach-Cherenkov cone in a supersonic flow, to the hydrodynamic formation of topological excitations such as quantized vortices and dark solitons at the surface of large impenetrable obstacles.

Luttinger-liquid behaviour in carbon nanotubes
Marc Bockrath,David Cobden,Jia Lu,Andrew G. Rinzler,Richard E. Smalley,Leon Balents,Paul L. McEuen +6 more
TL;DR: In this article, the authors present measurements of the conductance of single-walled carbon nanotubes (SWNTs) as a function of temperature and voltage that agree with predictions for tunnelling into a Luttinger liquid.
Journal ArticleDOI
A single-photon transistor using nanoscale surface plasmons
TL;DR: In this paper, the authors exploit the strong coupling between individual optical emitters and propagating surface plasmons confined to a conducting nanowire to realize strong nonlinear interactions at the single-photon level.
