Protocols and techniques for a scalable atom,photon quantum network

FORTSCHRITTE DER PHYSIK/PROGRESS OF PHYSICS, Issue 11-12 2009
L. Luo
Abstract Quantum networks based on atomic qubits and scattered photons provide a promising way to build a large-scale quantum information processor. We review quantum protocols for generating entanglement and operating gates between two distant atomic qubits, which can be used for constructing scalable atom,photon quantum networks. We emphasize the crucial role of collecting light from atomic qubits for large-scale networking and describe two techniques to enhance light collection using reflective optics or optical cavities. A brief survey of some applications for scalable and efficient atom,photon networks is also provided. [source]

Generation of photons on demand using cavity quantum electrodynamics

ANNALEN DER PHYSIK, Issue 1-3 2005
H. Walther
Abstract The paper gives a survey on recent experiments on the deterministic generation of photons. Experiments using Rydberg atoms in microwave cavities and trapped ions in optical cavities are discussed. The latter experiments show that lasers on the basis of single atoms are possible. [source]

Influence of the intracavity second harmonic generation on the mode competition in a double-mode diode-pumped Nd:YAG laser

LASER PHYSICS LETTERS, Issue 7 2005
V. M. Yermachenko
Abstract The influence of intracavity second harmonic generation on the mode competition in a double-mode diode-pumped Nd:YAG laser is studied theoretically and experimentally. Various configurations of the optical cavity with II-type phasematching frequency-doubling crystals are considered. The conditions of steady-state lasing and of lasing with a small level of amplitude pulsation in the output laser beam are determined. (© 2005 by Astro, Ltd.

Microphotonic header-recognition architecture for high-speed optical networks

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 1 2006
Muhsen Aljada
Abstract We demonstrate a MicroPhotonic optical header-recognition architecture based on delaying the optical headers within an optical cavity and detecting them using a photoreceiver array. The MicroPhotonic architecture overcomes the issue of optical interference encountered in conventional single-detector header-recognition structures. A 4-bit MicroPhotonic header-recognition architecture is simulated and experimentally demonstrated at 200 Mb/s. © 2005 Wiley Periodicals, Inc.
