We discuss recent progress in the study of the non-classical properties of light beams generated by non-degenerate parametric splitting in (2) nonlinear birefringent crystals, with special emphasis on their quantum correlation (twin beams). We describe experimental results using successively pure parametric fluorescence, parametric amplification of a weak signal beam pumped by a pulsed laser, and parametric oscillation in a cavity pumped by a cw laser. In this review, we compare the respective advantages and drawbacks of the different approaches. 相似文献

The collective phenomena of quantum interference, including wave particle duality and apparent non-locality, have intrigued
the physics community for many years. It is only recently that we have begun to turn these somewhat counter intuitive quantum
phenomena to good use. A leading force in that direction is quantum cryptography - absolute secure key exchange encoding data
on the polarisation or phase of individual photons, or using the quantum correlations between pairs of particles. Technologies
are now implemented to bring the various forms of quantum cryptography to commercial application. At the same time the possibility
of communications applications has stimulated the study of a variety of novel quantum interference phenomena. Quantum information
experiments involving two, three and four photons are planned and a novel Field of continuous variable (many photon) quantum
information has emerged. These various aspects of quantum cryptography are considered in the conference “QUICK: Quan- tum
interference and cryptographic keys: novel physics and advancing technologies", taking place in Cargese from April 7 to 13,
2001. Following that conference, we invite submission of original papers to a special issue of the European Physical Journal
D, on the following topics: - quantum cryptography technologies, - quantum cryptography systems, - free space quantum cryptography
and satellites, - pair-photon sources and multiphoton interference, - single photon sources, - continuous variable quantum
information, - security aspects, - cryptographic protocols, - entanglement purification in cryptographic schemes, - novel
physics and quantum gates for photonic qubits. The submitted articles should be sent to the EPJ D Editorial Office in Orsay.
The deadline is July 15, 2001. We look forward to a stimulating special issue. 相似文献

We report the generation of correlated photon pairs in the telecom C-band at room temperature from a dispersion-engineered silicon photonic crystal waveguide. The spontaneous four-wave mixing process producing the photon pairs is enhanced by slow-light propagation enabling an active device length of less than 100?μm. With a coincidence to accidental ratio of 12.8 at a pair generation rate of 0.006 per pulse, this ultracompact photon pair source paves the way toward scalable quantum information processing realized on-chip. 相似文献
