This work states that quantum interconnects, which convert quantum states from one physical system to those of another in a reversible manner, can be achieved by the optical interactions of single photons and atoms, allowing the distribution of entanglement across the network and the teleportation of quantum states between nodes.
Quantum State Transfer and Entanglement Distribution among Distant Nodes in a Quantum Network
We propose a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network. The transmission protocol employs special laser pulses…

Summary form only given. A particularly startling discovery by Bennett et al. is the possibility for teleportation of a quantum state, whereby an unknown state of a spin-1/2 particle is transported…
Photon blockade in an optical cavity with one trapped atom
Observations of photon blockade for the light transmitted by an optical cavity containing one trapped atom, in the regime of strong atom–cavity coupling represent an advance over traditional nonlinear optics and laser physics, into a regime with dynamical processes involving atoms and photons taken one-by-one.
Conversion of conventional gravitational-wave interferometers into quantum nondemolition interferometers by modifying their input and/or output optics
The LIGO-II gravitational-wave interferometers (ca. 2006–2008) are designed to have sensitivities near the standard quantum limit (SQL) in the vicinity of 100 Hz. This paper describes and analyzes…
Scalable photonic quantum computation through cavity-assisted interactions.
This work proposes a scheme for scalable photonic quantum computation based on cavity-assisted interaction between single-photon pulses that is robust to practical noise and experimental imperfections in current cavity-QED setups.
Strong interactions of single atoms and photons in cavity QED

An important development in modern physics is the emerging capability for investigations of dynamical processes for open quantum systems in a regime of strong coupling for which individual quanta…
High-Q measurements of fused-silica microspheres in the near infrared.
The observed independence of Q from wavelength indicates that losses for the WGM's are dominated by a mechanism other than bulk absorption in fused silica in the near infrared.
Ultrahigh-Q toroidal microresonators for cavity quantum electrodynamics (10 pages)
We investigate the suitability of toroidal microcavities for strong-coupling cavity quantum electrodynamics (QED). Numerical modeling of the optical modes demonstrate a significant reduction of the…
Generation of nonclassical photon pairs for scalable quantum communication with atomic ensembles
The first enabling step in the realization of a protocol for scalable long-distance quantum communication and the distribution of entanglement over quantum networks is reported, namely the observation of quantum correlations for photon pairs generated in the collective emission from an atomic ensemble.
