Entanglement and nonclassicality in four-mode Gaussian states generated via parametric down-conversion and frequency up-conversion

Multipartite entanglement and nonclassicality of four-mode Gaussian states generated in two simultaneous nonlinear processes involving parametric down-conversion and frequency up-conversion are analyzed assuming the vacuum as the initial state. Suitable conditions for the generation of highly entangled states are found. Transfer of the entanglement from the down-converted modes into the up-conv...

Entanglement in cascaded-crystal parametric down-conversion.

We use spontaneous parametric down-conversion in a cascade of crystals, driven by a single monochromatic cw pump laser, to study the interference of entangled photon pairs. By changing the distance between the crystals, the observed quantum interference pattern varies continuously from that associated with a longer single crystal to that associated with independent emissions from two distinct c...

Up and Down Frequency-Conversion Properties of Eu3+ Doped Lead Fluorophosphate Nanoglass Ceramics

Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...

Strong Spectral Entanglement in Spontaneous Parametric Down-Conversion

Photon pairs with a high degree of spectral entanglement have a very large capacity for carrying information. We describe methods for generating this type of entanglement and discuss applications. ! 2009 Optical Society of America OCIS codes: (270.5585) Quantum information and processing; (270.5565) Quantum communications. Spontaneous parametric down-conversion (SPDC) has proven to be a reliabl...
